ORGANIC THIN FILM TRANSISTOR

摘要

PROBLEM TO BE SOLVED: To provide an organic thin film transistor having a practical mobility.SOLUTION: An organic thin film transistor comprises: a primer layer between a gate insulator layer and an organic semiconductor layer. The primer layer is composed of (A) an organic silane thin film obtained by coating a composition containing: a) a hydrolytic condensate of an epoxy group-containing trialkoxysilane; b) polyamines; and c) c-1) n-pentanol or c-2) an organic acid of which pKa is in a range of 2.0-6.0 at 25°C, or alcohols having 2-5 carbon atoms, having a perfluoroalkyl group and/or a perfluoro alkylene group.SELECTED DRAWING: None
