The construction of functionalized donor unit based on benzodithiophene fused ring
Conjugated polymers based on donor-acceptor(D-A)structures have attracted extensive attention in the field of organic photovoltaics/photocatalysis.Screening for optimal D and A units is particularly important for the development of D-A conjugated polymers with excellent performance.The benzodithiophene(BDT)fused ring donor unit is one of the most successfully designed D units,and the design and development of a new functionalized BDT unit is of great significance to promote the development of high-efficiency D-A conjugated polymers.In this paper,the 2,5-position aldehyde group functionalized fused ring D unit material Methoxy-BDT-CHO was prepared by benzo[1,2-b:4,5-b']dithiophene-4,8-dione as the raw material,and the correct synthesis of the reaction intermediate and target product was demonstrated by 1H NMR.This work provides a good D-unit for the construction of high-efficiency conjugated polymers with D-A structure.
