摘要： A method of making a solid state semiconducting film. The method includes blending a non-conjugated semiconducting polymer matrix containing crystalline aggregates with intentionally placed conjugation-break spacers along the polymer backbone, and fully conjugated semiconducting polymer. The resulting blend is subjected to a film making method to result is a semiconducting film. A solid state semiconducting film comprising a non-conjugated semiconducting polymer matrix containing crystalline aggregates with intentionally placed conjugation-break spacers along the polymer backbone, and a fully conjugated semiconducting polymer, wherein the fully conjugated semiconducting polymer serves as tie chains to bridge crystalline aggregates from the non-conjugated polymer matrix. Devices made from these semiconductor films.

摘要： 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.

摘要： A composition for use as an electronic material. The composition contains at least one organic semiconducting material, and at least one electrically insulating polymer forming a semiconducting blend wherein the insulating polymer acts as a matrix for the organic semiconducting material resulting in an interpenetrating morphology of the polymer and the semiconductor material. The variation of charge carrier mobility with temperature in the semiconducting blend is less than 20 percent in a temperature range. A method of making a film of an electronic material. The method includes dissolving at least one organic semiconducting material and at least one insulating polymer into an organic solvent in a pre-determined ratio resulting in a semiconducting blend, depositing the blend onto a substrate to form a film comprising an interpenetrating morphology of the at least one insulating polymer and the at least one organic semiconductor material.
