Median alkoxy phenyl substituted and 2, 6 site strong electron donating group substituted BODIPY (4,4'-difluoro-4-bora-3a,4a-diaza-sindacene) derivative and preparation method thereof
By introducing a mid-position alkoxyphenyl group and a strong electron-donating group at positions 2 and 6 into boron fluoride complexed dipyrromethene derivatives, the conjugation effect and electron transmission performance of the dye are enhanced, and the problems of existing BODIPY dyes are solved. Deficiencies in absorption spectra and electron transmission enable broader spectral coverage and higher performance.

AI Technical Summary
After the existing boron fluoride complexed dipyrromethene (BODIPY) dye introduces substituent groups at the 2 and 6 positions, although the absorption spectrum is red-shifted, the conjugation effect and electron transmission performance are insufficient, which affects its application in the fields of life sciences and solar cells. expansion.
Design boron fluoride complex dipyrromethene derivatives substituted with alkoxyphenyl in the middle position and substituted with strong electron-donating groups at positions 2 and 6, and synthesize strong electron-donating compounds such as thiophene, bisbithiophene, fluorene and carbazole through a series of reactions. unit, enhance the conjugated chain length and electron migration effect of the dye, and broaden the absorption spectrum.
The absorption spectrum of the dye is significantly red-shifted, covering the entire visible light region, improving the hole mobility and electron transmission performance, and enhancing the spectral performance and stability of the dye.
