The structure–property relationship study of electron-deficient dihydroindeno[2,1-b]fluorene derivatives for n-type organic field effect transistors

Abstract

A bridged <italic>syn</italic> triphenylene derivative functionalized with dicyanovinylene units <bold>(2,1-b)-IF(C(CN)2)2</bold> has been synthesized, characterized and successfully used as an active layer in n-channel OFETs. Pseudo CMOS inverters made of n-type <bold>(2,1-b)-IF(C(CN)2)2</bold> -based OFETs have been fabricated.
