Abstract
Official abstract text for this publication.
Methods of making solid-state semiconducting films. The methods include forming a mixture by mixing at least two monomers in a pre-determined proportion such that at least one of the at least two monomers contains at least one non-conjugation spacer. Polymerization of the mixture is achieved by reacting the monomers with one another resulting in a solid state polymer which is then purified. The purified solid state polymer is dissolved in an organic solvent to form a homogenous solution which is then deposited onto a substrate, forming a solid-state semiconducting film by evaporating the solvent. Alternatively, the purified solid state polymer is deposited onto a substrate and heated to form a liquid melt, and cooling the liquid melt results in a solid state semiconducting thin film. Also, films comprising a semiconducting polymer composition containing a minimum of one non-conjugation spacer and devices comprising such films.
First claim
Opening claim text (preview).
The invention claimed is: 1. A semiconducting polymer composition comprising three monomers in a pre-determined proportion, wherein the three monomers are 3,6-bis(5-bromothiophen-2-yl)-2,5-bis(4-decyltetradecyl)-2,5-dihydropyrrolo[3,4-c]pyrrole-1,4-dione; 1,3-bis(5-(trimethylstannyl)thiophen-2-yl)propane; and 5,5′-bis(trimethylstannyl)-2,2′-bithiophene, wherein 1,3-bis(5-(trimethylstannyl)thiophen-2-yl)propane contains at least one non-conjugation spacer. 2. The composition of claim 1 , wherein the 3,6-bis(5-bromothiophen-2-yl)-2,5-bis(4-decyltetradecyl)-2,5-dihydropyrrolo[3,4-c]pyrrole-1,4-dione; 1,3-bis(5-(trimethylstannyl)thiophen-2-yl)propane; and 5,5′-bis(trimethylstannyl)-2,2′-bithiophene are in the mer ratio of: 1:x:(1-x), wherein x is the number of mers of 1,3-bis(5-(trimethylstannyl)thiophen-2-yl)propane. 3. A semiconducting polymer composition comprising two monomers in a pre-determined proportion, wherein the two monomers are 3,6-bis(5-bromothiophen-2-yl)-2,5-bis(4-decyltetradecyl)-2,5-dihydropyrrolo[3,4-c]pyrrole-1,4-dione, and 1,3-bis(5-(trimethylstannyl)thiophen-2-yl)propane, wherein 1,3-bis(5-(trimethylstannyl)thiophen-2-yl)propane contains at least one non-conjugation spacer.
