Chapter 340: Xu Qiu: Isn't that solved?

On Thursday, Master Xu, who was busy with the renovation of the Jiangwan laboratory, began to concentrate on writing his two articles... of course it was impossible.
As the small boss of the research group, all kinds of things encountered by other members of the organic photovoltaic field will eventually fall on Xu Qiu.
On the way to Caiyi 216, Han Jiaying took the initiative to say: "Brother, I tried the fluorination reaction of thiophene before, but the fluorine atom never got up."
"Is it the reaction to synthesize PBDB-T derivatives?" Xu Qiu asked.
"Yeah," Han Jiaying nodded: "To connect the fluorine atom to the thiophene unit of BDT."
Xu Qiu thought for a while and said, "I remember that the Shenzhen Optoelectronics Company has ready-made monomers to buy, and the H3x system used fluorinated BDT units before."
"That's right, but I bought 200 mg before. It was only enough to take two doses, and it was already used up." After a pause, Han Jiaying explained:
"I wanted to buy some more this time, but they said they were out of stock. Then if they want to buy it, they will have to make it for us. Only 1 gram will be sold. However, 1 gram of fluorinated BDT unit costs 9,000 yuan, ordinary BDT unit 1 gram only sells for about 1500, which is six times the difference. So I planned to synthesize and try it myself, but found that the fluorine atom can't get up."
"It's expensive to sell. There must be a reason. Most of it is difficult to synthesize and the yield is low. Let's go to the office and I will help you ask." Xu Qiu responded.
The two arrived at the office. Xu Qiu turned on the computer and retrieved the product catalog of Shencheng Optoelectronics. He found the number of the fluorine-substituted BDT monomer, which was BDT42. He also saw another type that had both fluorine substitution and sulfur atom side. The BDT unit of the chain, numbered BDT43.
Xu Qiu logged in to QQ, contacted the sales team, and sent a message: "BDT42 and BDT43 each buy 200 mg, and use it urgently."
After a few minutes, I received a reply: "Sorry, these two monomers are temporarily out of stock. If you want, we need to arrange someone from our company to synthesize, and sell them at 1 gram."
Upon seeing this, Han Jiaying handed over a look of "Look, I'm right."
Xu Qiu remained unmoved and continued to send messages: "We belong to the Wei Xingsi research group. This year, we published several articles on NC, AM, AEM, and EES. The name of your company was hung up in the experimental details, which is considered old. Customers, and 200 mg is only a preliminary attempt, if the effect is good, will continue to buy."
Xu Qiu didn't count this as a nuisance. He asked them to send a batch of polymer donor samples. Later, the PTAZ and P3TEA donor materials were repurchased.
After waiting for more than half a minute, the sales replied: "I just turned over the history records. It turned out that it was you. I can do it for you."
It has been a long time since Xu Qiu contacted the sales of the Deep City Optoelectronics company. Usually, Han Jiaying or Chen Wanqing did the work for buying materials at this store. Now it seems that his name is still somewhat useful.
Sales: "For 200 mg, BDT42 is 2200 and BDT43 is 2400. This is the best price. If possible, I will ask my colleagues in the synthesis department to do it for you."
Xu Qiu: "Yes."
Sales: "By the way, is there anything new in your team recently?"
Xu Qiu: "Well, the article has just been voted out. After a while, when the article is published, I will give you a copy of the PDF. It is not convenient to disclose too much at the moment."
Sales: "Understand, I have arranged the two materials for you, and will be synthesized next week and shipped to you as soon as possible."
Sales: "[Picture]"
Sales: "We have a new customer feedback activity this year. Any article published in the SCI area 1 and 2 after January 1 this year can apply as long as the experiment details mention that the drug was purchased from our company Receive bonuses, including 10,000 yuan for CNS articles, 1,000 yuan for articles in District 1, and 500 yuan for articles in District 2, which must be articles published this year to apply."
Xu Qiu: "Then I will count."
Xu Qiu opened the homepage of Wei Xingsi's research group. The information on this homepage was updated in real time as long as there are newly published articles at the request of Mr. Wei. According to Mr. Wei,
Only by decorating the facade can talents be attracted. Come and run."
I don’t know if I don’t count. Xu Qiu found out that there are a lot of articles this year. Except for the PCE11 AM that was published a year ago, other PCE11 derivatives, 3D-PDI, and ADA of the senior The receptor materials were all published after the year.
In total, there are three ACSAMIs, one JMCA, two AEM, one NC, one EES, and one AELM.
Among them, AELM is a new journal, and there is no division yet. The remaining eight articles, AEM, NC, and EES are all very good first-division journals, while ACSAMI and JMCA are all in the first division of the major category and the second division of the small category. Grouped into two areas, that is, a total of four articles with two areas and four articles with one area.
Xu Qiu downloaded the eight PDF files and sent them to the salesman, and said: "A total of four articles in the second area, and four articles in the first area, all from this year."
Sales: "Okay, please provide the account number of the bank card and the bank account opening branch of the bank card."
Xu Qiu: "622848..., the branch of Modu Comprehensive University."
Sales: "After the information is verified, we will put the bonus on the bank card."
After the chat with the salesman, Xu Qiu turned his head, rubbed Han Jiaying's hair, and said, "This will be solved, and I can get a bonus of 6000 yuan."
"Brother, are they not afraid of someone pretending to take it?" Han Jiaying wanted to understand as soon as she spoke, and then asked and replied: "We are all regular customers. We are basically clear, and every time we buy drugs, Go through the process of the drug warehouse, and then the reimbursement will also go to the school's financial office."
"Yes, the scientific research circle is so small, it's still more difficult to pretend to be a leader." Xu Qiu paused and judged: "It is estimated that their company has increased a lot of performance by relying on our articles this year, so it is so easy to talk. Also came up with this feedback activity."
After a while, other small partners in the research team also appeared one after another.
Han Jiaying went to the drinking fountain on the third floor to fetch water. Mo Wenlin saw the stitches and leaned towards Xu Qiu: "Can you teach me how to analyze the ternary blend system article."
"Yes," Xu Qiu nodded. Although he doesn't make the ternary blend system, he still understands a small branch of organic photovoltaics.
Xu Qiukan talked freely: "There are three general analysis ideas.
One is the complementarity of light absorption. Obviously, most systems will not choose a third component that overlaps the light absorption range of the binary system. You add PCBM and ITIC. With PCBM as the main body, you can say ITIC The addition of to broaden the light absorption range;
The second is the energy level structure. The cascade energy level is usually formed, that is, the energy level structure of the three components presents a ladder-like distribution. Your system is in the form of a cascade energy level, which can provide additional Charge transport channels, energy transfer, etc.;
The third is the morphology of the blended film. By adjusting the blend ratio of the two receptor materials, the morphology of the blended film is optimized.
In addition to these general ideas, if the performance of two donors or two acceptors is similar, it can also be said that they form a donor/acceptor alloy, but yours is ITIC or PCBM, and the performance gap is relatively large. Follow the previous three Just analyze the direction. "
"It turned out to be like this," Mo Wenlin recorded the points Xu Qiu said just now, making a stunned look, then pointed to a place on WORD and said: "Then Xu Qiu, how should I do this? ."
"This..." Xu Qiu just raised his head.
At this time, Han Jiaying's soft cough suddenly came from nearby: "Wen Lin, I will do this too, let me teach you."
Mo Wenlin was taken aback for a moment, then smiled and responded: "Okay, okay."
Han Jiaying sat down between Xu Qiu and Mo Wenlin, put down the water glass, and began to explain: "First... Then... Then... Finally... Wen Lin, see."
Mo Wenlin chuckled and nodded and said: "I understand, I understand, Jiaying is really amazing."
Xu Qiu couldn't help sighing beside him, the two are indeed good girlfriends, the relationship is really good.
After watching Han Jiaying and Mo Wenlin for a while, Xu Qiu was about to open WORD and start his own article, only to find that Wei Xingsi suddenly appeared at the door of 216: "Xu Qiu, have you read the last few documents? Come here to talk."
Xu Qiu had to go to 218 with more than a dozen documents. Recently, only two documents on organic photovoltaics are worth noting, both of which are non-fullerene systems:
Xu Zhenghong and his group published another IDTBR derivative on AM. By introducing a single fluorine atom on BT, IDTBR-F is obtained, but the efficiency has not reached a new high. The main selling point is the combination of P3HT donor material and IDTBR-F acceptor material, and an efficiency of 6.8% is obtained. Device stability is biased towards the concept of industrial application.
Another article published on ACSAMI, although the grade of the article is general, but the signal conveyed is worth noting. They imitated the IDT-ICIN before the school sister, synthesized a F8-ICIN material, the photoelectric performance is average, the efficiency is only 5%.
It seems that other people are also paying attention to the ICIN unit A. UU reading www.uukanshu.com has to say that the action is really fast.
The lecture on the literature lasted more than half an hour, nearly an hour.
Returning to the office, Chen Wanqing came to the door again: "Xu Qiu, the summary of my system article has been written, please help me take a look, OK?"
"Copy the U disk to me." Xu Qiu replied. Whoever makes himself a second game must be watched. Pushing is impossible.
After 20 minutes, Xu Qiu helped the senior sister to correct the summary, and by the way, simply changed the title, and then went to the bathroom to solve the physiological problem.
When I came back to see, the breathing light of the phone turned on. It was Wu Shengnan’s message: "I need to introduce alkyl side chains to synthesize IDIC. I want to buy halogenated hydrocarbons, bromohexane, can I help you buy it."
Xu Qiu helped her place a good order in the drug warehouse.
So, one morning passed, and Xu Qiu's own article didn't move a word.
PS: 3W8 short, 3W2 has been paid, 6K short.
