Abstract:
An organic thin film transistor (OTFT) comprising a self-assembled monolayer interposed between a gate dielectric and an organic semiconductor layer, the monolayer being a product of a reaction between the gate dielectric and a precursor to the self-assembled monolayer, the precursor comprising a composition having the formula:Xâ€”Yâ€”Zn, wherein X is H or CH3;Y is a linear or branched C5-C50 aliphatic or cyclic aliphatic connecting group, or a linear or branched C8-C50 group comprising an aromatic group and a C3-C44 aliphatic or cyclic aliphatic connecting group; Z is selected from â€”PO3H2, â€”OPO3H2, benzotriazolyl (â€”C6H4N3), carbonyloxybenzotriazole (â€”OC(&boxH;O)C6H4N3), oxybenzotriazole (â€”Oâ€”C6H4N3), aminobenzotriazole (â€”NHâ€”C6H4N3), â€”CONHOH, â€”COOH, â€”OH, â€”SH, â€”COSH, â€”COSeH, â€”C5H4N, â€”SeH, â€”SO3H, â€”NC, â€”SiCl(CH3)2, â€”SiCl2CH3, amino, and phosphinyl; and n is 1, 2, or 3 provided that n 1 when Z is â€”SiCl(CH3)2 or â€”SiCl2CH3.
