Abstract
Official abstract text for this publication.
An organic semiconducting donor-acceptor (D-A) small molecule, as well as a semiconductor device that can incorporate the D-A small molecule, are disclosed. The D-A small molecule can have electron deficient substituents and R group substituents that can be C 1 -C 20 linear alkyl chains, C 2 -C 24 branched alkyl chains, hydrogen atoms, etc. The D-A small molecule can be can be synthesized in a reaction between a dithienofuran (DTF) core monomer and an electron deficient monomer. Additionally, the D-A small molecule can be part of an organic semiconducting copolymer. A semiconductor device that can incorporate the D-A small molecule in a photoactive layer is also disclosed herein. Additionally, 3,4-dibrominated furan compound that can, in some embodiments, be a precursor for the D-A small molecule is disclosed. The 3,4-dibrominated furan compound can be synthesized in a reaction involving a furan-2,5-dicarboxylic dimethyl ester (FDME), which can have a bio-renewable precursor.
First claim
Opening claim text (preview).
What is claimed is: 1. A semiconducting compound with a formula of: wherein each R is a substituent selected from a group consisting of a C 1 -C 20 linear alkyl chain, a C 2 -C 24 branched alkyl chain, and a hydrogen atom; wherein E is an electron deficient substituent; and wherein the semiconducting compound is synthesized in a reaction between an electron deficient monomer and a dithienofuran core monomer, wherein the electron deficient monomer is selected from a group consisting of bromoalkylthienyl-pyridylthiazoles, benzodithiazoles, pyridyldithiazoles, diketopyrrolopyrroles, thienothiophene esters, fluorinated thienothiophene esters, dithienotetrazines, thienoquinoxalines, benzoquinoxalines, pyridylquinoxalines, and thienopyrrolodiones, and wherein the dithienofuran core monomer has a 3,4-dibrominated furan precursor with a formula of: wherein each R is a substituent selected from the group consisting of the C 1 -C 20 linear alkyl chain, the C 2 -C 24 branched alkyl chain, and the hydrogen atom, and wherein the 3,4-dibrominated furan precursor is synthesized in a reaction involving a furan-2,5-dicarboxylic dimethyl ester having a bio-renewable precursor selected from a group consisting of a sugar and an aldaric acid.
