Direct access to 4,8-functionalized benzo[1,2-b:4,5-b′]dithiophenes with deep low-lying HOMO levels and high mobilities

Abstract

A methodology for versatile and direct access to 4,8-functionalized benzo[1,2-<italic>b</italic>:4,5-<italic>b</italic>′]dithiophenes with high mobilities is developed.
