Polymorphism in 9,9-diarylfluorene-based organic semiconductors: influence on optoelectronic functions

Abstract

Polymorphism is observed in 9,9-diarylfluorene-based organic semiconductors. The effects of rich phase behavior on the charge transport and photoluminescence properties of these semiconductors are investigated. Polymorphism control is a rational way to tailor the optoelectronic functions of their films.
