Abstract

A thin film made of organic semiconducting molecules of diphenyl derivatives dinaphthothienothiophene (DPh-DNTT) has high carrier mobility especially in the form of single layer. However, the carrier mobility can be significantly affected by molecular orientation of DPh-DNTT. Here, we present the molecular orientation analysis of single-layer DPh-DNTT by polarization Raman measurement. We analyzed the relation between the Raman intensity and polarization of incident light, and correlated them with the molecular orientation. We successfully obtained molecular orientation image of an island domain of single-layer DPh-DNTT, and revealed that they have a similar orientation within the domain.
