I Have a Research Support System

Brother, how are you doing? Han Jiaying turned her head and asked.

Xu Qiu put down the silicone plate and ultraviolet lamp in his hand, and said: This spot plate is one deep and one shallow, and there are other shallow shadows. The shallow ones are raw material spots, and the deep ones are most likely products.

There is only one dark product spot, so the yield should not be low. Han Jiaying responded while dipping the solution with a capillary tube, and dotted it vertically on the silica gel plate.

Xu Qiu hummed, It's a bit beyond my expectation. I originally expected 50% to be good, but now it seems that it may be closer to 70-80%.

Then, he picked up another silicone plate, illuminated it with a UV lamp, and said, My other reaction, the result of spotting the plate is similar, how about yours?

It should be a success. There is one product that is darker, not much miscellaneous, and the raw material is shallower. However, to carry out the next reaction, you still have to pass through the pillar. Han Jiaying paused and said:

I feel that the reaction of small molecules and the synthesis of products are only the first step in the long march, and the subsequent separation and purification are troublesome.

Yes, Xu Qiu nodded, Slightly changing the molecular structure, changing to a different system, the conditions used will be different, if a little bit of impurities are mixed in, it needs to be purified again, so we must be careful every time Fortunately, there is a high-pressure liquid chromatograph in the laboratory, which can greatly improve the efficiency of experiments.

After some effort, the two men processed the reactions and obtained four sets of crude products.

Xu Qiu stood by the sink, handling the used glass instruments, and asked casually, What time is it?

Hmm... Han Jiaying was cleaning out the fume hood, she glanced at the stopwatch hanging beside the fume hood, a quarter past five. There is no clock on the wall in the laboratory, and you usually don't bring your mobile phone in, the stopwatch It is a commonly used timing tool.

Once the liquid chromatograph is turned on, it must run continuously for at least one and a half hours, or even two hours, which is too long. Xu Qiu thought for a while and said, If we pass the column now, there is not enough time, let's talk about it after dinner.

Okay, Han Jiaying naturally had no objection, I've already sorted it out here, how about you, brother?

It will be ready soon. Xu Qiu sped up the movement of his hands a little, one minute.

The schoolgirl walked to his side, Then I'll wait for you.

After tidying up the laboratory, the two returned to the office.

Han Jiaying sat on the sofa with one hand resting on her chin, her gaze wandered around Xu Qiu, wondering what she was thinking about.

Xu Qiu didn't notice her abnormality. After washing his hands, he went back to his desk and sat down, thinking about the night's experiment plan in his mind.

'My two products are both products of the last step, that is, 3D-PDI molecules. After purification, they can be directly used for device testing. They can be separated and purified first tonight, and then directly put into the simulation laboratory to test their performance. '

‘In addition, the monobromine substitution products of PDI-5 and PDI-6 molecules have bottomed out, and another batch will be synthesized. '

'Also, PDI-8, a PDI molecule with a longer side chain, can also be synthesized into a batch for use...'

Brother~ The voice suddenly rang in Xu Qiu's ear, pulling him back to reality.

As soon as he raised his head, Han Jiaying came to him at some point. Her face was reddish, and she leaned on the glass of the desk partition with one hand. The air conditioner in the room was always on. .

Xu Qiu settled down, What's the matter?

Han Jiaying hesitated for a few seconds, then mustered up her courage and said:

Brother, can we... be together?

Xu Qiu's body suddenly trembled, and his brain began to run rapidly:

'Fuck, the junior girl confessed to me, so suddenly. '

'It didn't seem so sudden, we seemed to have crossed the line of friends a long time ago. '

‘Promise, promise or promise? '

‘The three options are the same length, choose C. '

'How should I respond? '

'%@\u0026*%...'

'I hate myself for not being Tao Yan, I have no experience at all. '

But it can't be dragged on forever, it can only be like this...

Thousands of words finally merged into one word, and Xu Qiu said: Okay.

Han Jiaying looked shy, and opened her arms slightly, making a gesture of begging for a hug.

Xu Qiu was tall and burly, so he picked up the junior princess and threw her on the bed. (delete this line)

...

After more than an hour.

The two went to the cafeteria to finish their dinner, and then returned to the micro-analysis building.

Take a break and continue experimenting.

Xu Qiu talked about his previous division of labor plan, and Han Jiaying naturally had no objections.

However, due to some... small accidents in the middle, they were a little rushed.

Fortunately, the departure time of the last school bus was delayed to 9:30 after the start of school, half an hour more experiment time than the previous days.

In the end, Xu Qiu used liquid chromatography to separate and purify his two samples, and successfully obtained two 3D-PDI molecules with yields of 76% and 71% respectively, and the yield was close to 100 mg.

As soon as he got the materials, he immediately copied them into Simulation Lab II, handed over to the simulation experimenters to prepare devices, and traversed the existing donor library.

Han Jiaying submitted three reactions, namely the bromination reaction of PDI-5 and PDI-6, and the synthesis reaction of PDI-8.

Each of the first two reactions puts in 1 gram of the reaction raw material, and the reaction time is about two hours.

She spots the plate every once in a while to detect real-time products. Because she has experience and knows the product information corresponding to each sample point, she can stop the reaction in time when the monobrominated product is the most.

Theoretically, the yield will be higher than that of the last reaction, but the time is limited. These two reactions only reached the step of product mixing, and then stopped.

In the third reaction, 5 grams of reaction raw materials were cast, and the reaction time was 24 hours, which required the next day to be processed.

...

On the school bus.

After the two confirmed their relationship, they naturally snuggled together.

Han Jiaying said in a low voice, Brother, do you want to make our relationship public?

Xu Qiurou said: I can do it, what do you think? For him, love is something that only belongs to two people, and other people's opinions are not important at all, and it doesn't make any difference whether it is open or not.

I think we should keep a low profile in the group, in private... Han Jiaying paused and said, Anything is fine.

It's up to you. Xu Qiu fondled her hair.

Brother~ I'll sleep for a while, call me when I get to school. After speaking, Han Jiaying shrank into his arms.

Okay. Xu Qiu also closed his eyes, and began to think about the past with his school girl.

Today's confession was a bit sudden, but it seemed like everything was going to happen naturally.

The relationship between the two has become much closer, kissing, hugging and holding high. These couples do it every day, except for the last step...

The terms of addressing each other have not changed. Xu Qiu would always feel too ashamed to use pet names like baby and baby, mainly because school girl and senior brother are easy to use.

After thinking wildly all the way, the school bus finally arrived at the Handan campus and stopped slowly.

Xu Qiu shook the junior girl awake, and the two of them walked back to the dormitory slowly holding hands.

...

the next day.

Xu Qiu got the results of the simulation laboratory II early in the morning. The 3D-PDI molecule he synthesized had a maximum efficiency of 4.37%.

This data is not bad, and it has surpassed the JACS of the previous review, with an efficiency of 4%.

If the results are sorted out, it should be no problem to post an article in the second section, but it is not easy to post an article in the first section, which is the disadvantage of losing the opportunity.

Moreover, even if you want to post to the second district, it will take about a month to do experiments and write articles, or even more.

There is no way to do this. To do research related to the synthesis of small organic molecules, the fixed time cost is too long.

The quality of articles is more important to him now, and there is no shortage of articles from the second district.

In order to complete the system advanced tasks, three SCI first-division articles need to be published. In addition to the received AM, there is also a revised AEM, which means that he still lacks one first-division article.

If the efficiency is further raised to 6% or 7%, there will be a chance to rush to a district.

If it can reach 8%, it is close to the world record, and the first area is very stable. If you keep an AEM, there is a high probability that AM will go up.

If it can reach more than 10%...

Although the possibility is extremely low, if it reaches 10%, it is almost possible to publish a major sub-journal of Nature, which can be regarded as a breakthrough, which means that non-fullerene receptors have entered the stage of history.

Of course, if you want to publish a CNS main journal, 10% is far from enough. From the perspective of efficiency alone, it must be more than 15%, and there is still a lot of preliminary work.

Therefore, without thinking too much, Xu Qiu decided to continue improving the molecular structure.

In fact, he had considered using Simulation Lab II to help him optimize the molecular structure, but he did not do so after careful consideration.

On the one hand, the cycle of synthesizing a molecule is very long, involving multi-step reactions, which may take one day, two days or even longer. Even if multiple reactions are carried out at the same time, on average, one molecule is completed in one day, and the points are consumed too quickly.

On the other hand, if the system is used to prepare devices in batches to explore the photoelectric properties of materials, because there are multiple device laboratories in the simulation laboratory, the time for cleaning the substrate, spin-coating the transport layer, and evaporation can be ignored. Considering the spin-coating time, one piece per minute and sixty pieces per hour are also one day, and thousands of conditions can be explored.

Based on the current situation of Simulation Lab II, he has also planned his future cooperation model with the school girl——

He mainly makes devices in Handan, and his junior is mainly responsible for synthesis in Zhangjiang.

Such a plan can make efficient use of the laboratories on both sides of Handan and Zhangjiang, and increase the work efficiency by at least 50% compared with the two stacked together.

This is also the reason why Xu Qiu took her through every experiment before, in order to train her into an organic synthesis experiment talent who can stand alone, paving the way for the promotion of this cooperation model.

Originally, such an arrangement didn't matter, but now the two are suddenly together.

It's very pit...

On the second day of dating, they were forced to go to another place, and they had to find someone to reason with.

It can only be said that God's will tricks people.
