Patent ID: 8530270

Claim:
A method for preparing a thin film transistor device comprising the steps of: A) depositing a gate insulator layer on a electrically conducting substrate, and B) depositing a layer of an arylene diimide precursor that is a non-polymeric amic acid or amic ester on the gate insulator layer, the layer further comprising an amine or acid anhydride catalyst in an amount of at least 0.5 weight % based on the weight of the non-polymeric amic acid or amic ester, wherein the arylene diimide precursor is represented by any of the following Structures (I), (II), and (III): wherein Ar is an anthracene, naphthalene, or perylene nucleus and the four carbonyl groups are attached directly to peri carbon atoms, A 1 is an aryl, heteroaryl, non-aromatic alkyl, fluoroalkyl, alkylaryl, cycloalkyl, or heterocyclyl group, and R is hydrogen or an alkyl or cycloalkyl group that is the same or different from that of A 1 , wherein for Structure (II), Ar is a nucleus as defined above for Structure (I) and the four carbonyl groups are attached directly to peri carbon atoms, A 1 and A 2 are independently aryl, heteroaryl, non-aromatic alkyl, fluoroalkyl, alkylaryl, cycloalkyl, or heterocyclyl groups, and R is hydrogen or an alkyl or cycloalkyl group that is the same or different from that defined for A 1 and A 2 , and wherein for Structure (III), Ar is a nucleus as defined above for Structure (I) and the four carbonyl groups are attached directly to peri carbon atoms, A 1 is as defined above for Structure I and R is as defined above for Structure I and is the same or different from that defined for A 1 .
