The development of bioimaging technol. in recent years has shown that second near-IR (NIR-II) fluorescence imaging (FI) is gradually replacing the traditional visible light and first near-IR (NIR-I) FI. In the NIR-II window, the light absorption, autofluorescence and scattering of biol. tissues are significantly reduced, which strongly promotes the design, development and application of contrast agents with NIR-II emission capabilities. However, the NIR-II bioimaging technol. is still incomplete, in the initial stage, and has high research value. In order to increase the quantum yield (QY) of D-A polymers, we used thiophene, 3-methoxythiophene, 3,4-ethylenedioxythiophene (EDOT), 3-hexylthiophene and 3-(2-ethylhexyl)thiophene as strong electron donors and designed and synthesized NIR-II organic polymers P1, P2, P3, P4 and P5, which are of great significance to the mol. design of D-A conjugated polymers. Finally, we explored the FI of the polymers in vivo and in vitro, and verified our idea of increasing the QY. In the part of experimental materials, we found many familiar compounds, such as 2,5-Dibromothiophene(cas: 3141-27-3Application of 3141-27-3)
2,5-Dibromothiophene(cas: 3141-27-3) , is mainly used as pharmaceutical intermediate and synthesis intermediate. 2,5-Dibromothiophene may be used in the preparation of soluble α,ω-diformyl-a-oligothiophenes.Application of 3141-27-3
