Air-stable N-type organic microribbon transistors based on perylene diimides derivatives

Abstract

We report a new type of organic microribbon via solution phase self-assembly from a conjugated small molecule N,N'-bis[2-(4-fluoro-phenyl)-ethyl]-3,4,9,10-perylenetetradicarboximide (4F-PEPTC) for use in organic field effect transistors. Devices based on a network of 4F-PEPTC microribbons show a typical n-channel field effect behavior with average current ratio > 103 and exhibit excellent air stability in ambient air over 30 days.
