POLYMER, ORGANIC FILM CONTAINING IT, AND TRANSISTOR

摘要

PROBLEM TO BE SOLVED: To provide an organic thin film containing a bisthiazole polymer having excellent solubility, air stability, high mobility, and a high ON/OFF rate, and to provide an organic thin film transistor. SOLUTION: The polymer contains a structure unit represented by general formula 1. In the formula, R1, R2, R3, and R4each represents a hydrogen atom, a halogen atom, a substituted/unsubstituted alkyl/alkoxy group, or a thioalkoxy group and may be the same or different from one another, and at least one of R1, R2, R3, and R4has a substitute other than hydrogen. In the formula, n is an integer of 1 or greater, and if n is 2 or greater, R3and R4are the same or different groups. COPYRIGHT: (C)2009,JPO&INPIT
