摘　　要：基于供体-受体(D-A)结构的共轭聚合物在有机光伏/光催化领域引起了广泛关注.筛选优异D、A单元进行搭配对开发性能优异的D-A结构共轭聚合物尤为重要.苯并二噻吩(BDT)稠环供体单元是目前设计最为成功的D单元之一,设计开发新型功能化的BDT单元对推进高效率D-A结构共轭聚合物的开发具有重要意义.本文以苯并[1,2-b:4,5-b′]二噻吩-4,8-二酮为原料,先后经过羰基还原、质子转换和Bouveault醛化三步合成反应,制备得到了2、5位醛基功能化的稠环D单元材料Methoxy-BDT-CHO,通过1H NMR表明了反应中间体及目标产物的正确合成.该工作为高效率D-A结构共轭聚合物的构筑提供了良好D单元.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.
