I Have a Research Support System

In the evening, Wei Xingsi took Tang Yunkun somewhere to have fun.

Xu Qiu returned to 216 and learned that the senior sister's device results today had the highest efficiency of 1.11%.

On the way to the cafeteria, Xu Qiu and Chen Wanqing walked side by side, the senior sister didn't want to talk.

But this time she wasn't as lost as she was when she synthesized C1 before, she seemed quite calm.

Maybe he didn't put too much hope in himself, or he got used to it?

Sister, what do you plan to do next? Xu Qiu asked casually.

Chen Wan gave him an innocent look, opened and closed her mouth, but no sound came out.

The efficiency of 1% is not the worst in A-D-A. I have seen some articles made of organic photovoltaic materials, but they dare not even release the efficiency. They only made field-effect transistor devices. The mobility of materials It’s not low, and it can still be published.” Xu Qiu tried to cite examples to comfort the senior sister, but seeing that there was no effect, he continued to analyze:

Sister's system is at least a new structure. If you complete the characterization data, you should still have a chance to submit an article on Macromol. Chem. Phys. in the third district.

Seeing that she still didn't say a word, Xu Qiu said to himself: It's just the title of senior sister. It needs to be changed. It used to be 'killer in the second district', but now it's 'killer in the second and third districts'.

Chen Wanqing chuckled, and immediately glared at Xu Qiu, If you can talk, talk more.

Afterwards, she sighed softly, Let's talk about it, if you really want to write an article, every intermediate product needs to be supplemented with a bunch of NMR, elemental analysis and other data. It doesn't feel worthwhile for an article in the three districts.

That's true. Xu Qiu responded with a nod. The senior already has four articles for the second district, so she is naturally unwilling to spend a semester for an article for the third district.

In fact, the four articles of the senior sister in the second section are considered conservative estimates. Like the JMCA she posted, they are not strictly the articles in the second section, but in a superposition state of the first section and the second section.

Because domestic journals are usually divided according to the Chinese Academy of Sciences, each journal has a major category and several minor categories according to its positioning, and the major and minor categories are independently judged, and there may be differences.

Take JMCA as an example. In the major category, it is the first area of ​​engineering technology, and it is the top of the first area. In the small category, it is material science: the second area of ​​comprehensive, the second area of ​​physical chemistry, and the first area of ​​energy and fuel.

Some schools divide periodicals according to major categories, so JMCA is a district;

Some are based on the subcategory closest to the department, such as the Department of Materials, according to Materials Science: Comprehensive category, then JMCA is the second district.

There are also those who belong to the research group and give themselves gold, no matter the major category or the small category, they will all follow the highest one, that is, regardless of the journals of the first section of the major category and the second section of the small category, or the first section of the small category and the second section of the major category, all journals will be published. It can be claimed as a district to the outside world.

Obviously, this kind of journals with different major categories and subcategories, even if they are classified into one district, will still be at the bottom of the same district, and the probability is not as good as that of journals with both major categories and small categories in one district.

For example, an AM article and an AEM article published by Xu Qiufa are both Top of the first section of the engineering technology category, and both are in the first section of the five or six sub-categories. The kind that doesn't go wrong.

In addition, the influence of journals will change over time, so the division is not static. It will be re-evaluated every year according to the influence of journals, with ups and downs.

For example, the macromolecules journal is an old-fashioned journal founded in 1968. It used to be the top journal in the field of polymers, but now its influence has declined very seriously. At present, the major category is the Top of the second area of ​​chemistry, and the sub-category is the first area of ​​polymer science. .

For another example, the journal Polymer was also founded in 1960, and now it has been reduced to the third section of the major category of chemistry, and the second section of the minor category is polymer science.

It stands to reason that this kind of name named after a single word is usually very NB existence, such as the top CNS, Cell, Nature, Science, but as time goes by, a new generation replaces the old one , There are always some old journals with broken godheads, falling from the highest status to the mortal world.

It can only be said that the world is impermanent, and the back waves are too fierce.

After dinner, Wu Feifei, Tian Qing, and Duan Yun went back to the bedroom to rest, while Xu Qiu, Chen Wanqing, and Sun Wo returned to 216.

Chen Wanqing adjusted her mentality and decided to temporarily put down the C1 and C4 systems to prepare for the subsequent experiments.

She took the initiative to find Xu Qiu and asked, I plan to redesign the molecular structure of A-D-A and re-plan the synthetic route. Besides introducing strong electron-withdrawing groups such as cyano groups and fluorine atoms, do you have any other suggestions?

Xu Qiu was chatting with the school girl on the computer WeChat, but when he heard the call from the school girl, he used two things at once, typing and posting emoticons while thinking, and after a while, he raised his head and said:

Leaving aside the problem of poor photoelectric performance of the material, I think the main problem of the senior sister is that the previous synthesis path is too long. It takes six or seven whole days to complete the synthesis, and once the synthesis fails midway, it has to start from scratch, so I I feel that it is necessary to shorten the reaction steps.

That's true. I didn't know what to think at the time, and came up with more than a dozen steps of synthesis. Chen Wanqing shook her head, and then said:

I already have a preliminary idea about this. After I plan to design the structure of the A unit, I will first go to the major reagent manufacturers to search to see if there are any useful intermediates that can be purchased directly to reduce the synthesis steps. .”

That's the reason, Xu Qiu responded, Just like the 3D-PDI system I'm making now, there are only 5/6/8 series, but no 7 series. Goods, it’s too difficult to synthesize by yourself.”

Hmm, Chen Wanqing nodded, and asked, Any other suggestions?

After discussing with Tang Yunkun today, I also had some inspiration, Xu Qiu paused and said:

When designing an A-D-A acceptor molecule, it is also necessary to consider the degree of fit between its HOMO/LUMO energy level structure and the donor material. As far as I understand, the energy level structure of the final acceptor material is mainly determined by the central D unit. , and the stronger the electron-withdrawing ability of the A unit, the narrower the band gap and the deeper the HOMO/LUMO energy level.

I think this is also the core advantage of A-D-A molecules. The band gap and light absorption range can be easily adjusted.

I'll think about it, Chen Wanqing nodded thoughtfully, You can use DFT to simulate it before doing it.

After a while, she asked expectantly, Student, is there any more?

It's gone, it's gone, you've sucked out all your inspiration, Xu Qiu said angrily, Why don't I just draw the molecular structure for you?

That's a good thing. Chen Wanqing answered.

Do you look like a senior? Xu Qiu shook his head and said helplessly, When you design the synthetic route, show me.

Okay, it's a deal. Chen Wanqing's eyes lit up.

...

Friday.

The first and fourth parts of the review article have been integrated by Xu Qiu and Chen Wanqing, and the abstract part has also been written.

Since the review usually has no supporting information (SI) and pictorial abstract (TOC), the equivalent of the main text has basically been written.

There is still a lack of reference sorting, Cover Letter, and the unique copyright use application (Copyright) and personal introduction (CV) of the review article.

The work of sorting the references was handed over to Han Jiaying who was far away in Zhangjiang;

I wrote the cover letter once when I was writing the review proposal, and I just used it to modify it. It took Xu Qiu less than half an hour to complete it;

Chen Wanqing undertook the task of applying for copyright use.

All images appearing in the review and citing other documents must apply for copyright use.

The three major journal companies, RSC, ACS, and Wiley, have different procedures for applying for copyright use, but they are generally similar.

Self-reporting on the Internet, including the journal, year, volume number, issue number, page number and other information of the cited literature, as well as the title, author, contact information, publisher and other information of the reviewed literature.

The web page is automatically reviewed, and the PDF version of the Copyright file can be directly obtained after passing the review.

Finally, combine all the PDFs into one large PDF file and upload it as a single attachment when submitting your manuscript.

In the personal introduction section, review articles usually have it, and some Article type articles also have it, that is, add all or part of the author's personal introduction, including a color photo, to the article.

In the profile section of this review, there are only three places, while the authors have five.

Xu Qiu, Chen Wanqing, and Han Jiaying co-authored the first article, the fourth author Tang Yunkun linked to the newsletter, and the fifth author Wei Xingsi linked to the newsletter. Generally, for articles with double or multiple letters, the corresponding author ranked last is the first corresponding author.

Obviously, among the three places, Wei Xingsi and Tang Yunkun each had to get one, and the last place naturally fell on Xu Qiu.

As for the situation where Xu Qiu, Chen Wanqing, and Han Jiaying each get a spot, it is of course impossible.

This is the default rule in academic circles.

Because Tang Yunkun and Wei Xingsi are both professors, they have published reviews before, and there are ready-made versions of their personal profiles, so they can be used directly, or slightly modified and supplemented.

For example, Teacher Wei's profile:

In XX, Wei Xingsi received a Ph.D. in polymer science from the Department of Materials Science and Engineering, Pennsylvania State University. From XX to XX, he studied for a postdoctoral fellow at Cambridge University... In XX, he joined the Department of Materials Science, Shanghai Comprehensive University. Now, the main research directions of Professor Wei Xingsi's research group are organic and perovskite solar cells and organic/inorganic hybrid thermoelectric materials.

Teacher Tang's personal profile is also similar, including education and scientific research experience starting from Ph.D., as well as current work unit and main research direction.

Xu Qiu originally planned to apply his template directly, but after thinking about it carefully, he has not even graduated from a bachelor's degree, and he has not yet obtained a bachelor's degree, so he can't write his experiences in junior and high school.

After much deliberation, he only wrote three sentences: Xu Qiu, an undergraduate student at Shanghai Comprehensive University, is currently a student of Professor Wei Xingsi, and his main research direction is organic solar cells.

No experience, quite easy.

After completing the personal profile, Xu Qiu continued to improve the review article.

This time it is a dual corresponding author, involving multiple work units, and it is necessary to fill in the personal information and work units of Mr. Tang.

In addition, in the part of the final acknowledgment of the article, the number of the National Natural Science Foundation of China that supported Mr. Tang should also be thanked, which cannot be omitted.

The organic trio worked together and finally finished a full draft version of this review before leaving get off work in the afternoon.
