Contrasted behaviours of methylthiolated perylene and pyrene as organic semiconductors: implications of molecular electronic structure and crystal structure

Abstract

Prompted by 1,3,6,8-tetrakis(methylthio)pyrene (MT-pyrene) showing the ultrahigh mobility in its single-crystal transistors, we have synthesized and characterized its closely related compound, 2,5,8,11-tetrakis(methylthio)perylene (MT-perylene).
