Embodiment Construction

[0067] A feature of the present disclosure is to provide p-type semiconductors of the general formula exemplified herein for use in microelectronic device applications, such as TFT devices.

[0068] Another feature of the present disclosure is to provide a p-type semiconductor of the general formula exemplified herein with a bandgap of about 1.5 eV to about 3 eV (as determined by the absorption spectra of its thin films).

[0069] In an additional feature of the present disclosure, p-type semiconductors of general formulas I and II exemplified herein are provided for use as microelectronic components, and the polymers are dissolved in conventional organic solvents such as dichloromethane, tetrahydrofuran, toluene , xylene, mesitylene, chlorobenzene, dichlorobenzene, trichlorobenzene, etc. have a solubility of, for example, at least about 0.1 wt% to about 95 wt%, and thus these polymers can be prepared by solution processes such as spin coating, screen printing , embossing, dip...

Abstract

An electronic device containing a polymer of Formula (I), Formula (II), or mixtures, or isomers thereof wherein each R 1 through R 10 is independently hydrogen, alkyl, aryl, alkoxy, halogen, arylalkyl, cyano, or nitro providing that R 1 and R 2 exclude halogen, nitro and cyano; a and b represent the number of rings; and n represents the number of repeating groups or moieties.

Description

[0001] Statement Regarding Federally Funded Research or Development [0002] This electronic device and certain components thereof were sponsored by United States Government Cooperative Agreement No. 70NANBOH3033 signed by the National Institute of Standards and Technology (NIST). The US Government has certain rights in the devices and certain semiconductor components illustrated below. technical field [0003] The present disclosure generally relates to semiconductors of the general formula exemplified herein and produced, for example, from monomers comprising two tertiary amines and two thieno groups which are primarily stabilizing, methods of preparation and their use. More specifically, the present disclosure relates, in embodiments, to novel polymers of the general formula exemplified herein and produced, for example, from monomers comprising mainly two tertiary amines for stabilization and in the monomer Two thieno groups per terminal, wh...
