3,3"-Difluoro-5,5"-bis(trimethylstannyl)-2,2"-bithiophene is used for the synthesis of small molecules or polymer semiconductors in organic electronic applications, such as P(NDI2OD-T2F).
It is believed that, by introducing heteroatoms such as fluorine on the backbone of polymer structures, the crystalline properties of the conjugated polymers can be enhanced, resulting in a higher degree of orientation of such polymer structures with optimised domain size in blended thin films with either fullerene or non-fullerene acceptors.
This product has been used in our own lab by Ossila chemists for the synthesis of PBDD4T-2F.

ps:大皿和6孔板里细胞密度、培养条件等等都几乎一样。
我看园子里有人提过类似的问题,但还没人给出答案,希望有经验或有想法的战友帮忙分析分析啊~谢谢!
各位战友,小弟刚开始养细胞,但是细胞状态一直不好,最近一次传代后,一传二,居然两个皿里细胞状态完全不同,第一个皿还能看见细胞的形态,而第二个皿几乎看不见贴壁的细胞,请问大家遇见过这种情况吗?
实验需要请问有没有养THP-1细胞的同仁?能否寄一皿我,我在广州南方医科大学,不胜感激!
所谓上皿式指的是称量盘在支架上面;而称量盘吊挂在支架下面的为下皿式。
目前使用较为广泛的是上皿式电子天平。
同学说传代必须是一皿传多皿,一皿传一皿就不算传代~求高手指点~~
传代后5天,依然没有长满,怕影响活力,想传代和冻存,不知这样是否可以??
激光共聚焦的看活细胞皿哪里买呢
