Patent ID: 6946676

Claim:
An organic thin film transistor (OTFT) comprising a polymeric layer that is substantially nonfluorinated having a thickness less than about 400 Å, which forms an interface interposed between a gate dielectric and an organic semiconductor layer, wherein the polymeric layer comprises a polymer having interpolymerized units according to the formula: in an amount from about 50 to 100% of said interpolymerized units; and from 0 to about 50% of said interpolymerized units according to the formula: wherein each R 1 and R 2 comprises, independently, a group selected from hydrogen; C 1 -C 20 aliphatic; chloro; bromo; carboxy; acyloxy; nitrile; amido; alkoxy; carboalkoxy; aryloxy; chlorinated aliphatic; brominated aliphatic; C 6 -C 20 aryl; C 7 -C 20 arylalkyl; hydroxy when different R 1 and X groups are included; and combinations thereof which may contain one or more heteroatom(s) and/or one or more functional group(s); each X, independently, comprises a functional group capable of bonding to the gate dielectric; and any combination of at least two R 1 , R 2 , and/or X groups may together form a cyclic or polycyclic aliphatic, aromatic, or polycyclic aromatic group; and d) combinations thereof.
