The present invention relates to a charge transporting semi-conducting material comprising: a) optionally at least one electrical dopant, and b) at least one cross-linked charge-transporting polymer comprising 1,2,3-triazole cross-linking units, a method for its preparation and a semiconducting device comprising the charge transporting semi-conducting material.

A thermally stable and solvent resistant conductive polymer composite and its manufacturing friendly preparation method are disclosed. The disclosed composite presents great electrical conductivity with thermal stability and solvent resistance. A method of mixing a host thiophene conjugated polymer and a crosslinkable silane precursor simultaneously introduces both dopant and rigid cross-linked siloxane network into polymer system. The thin film made by the disclosed thermally stable and solvent resistant conductive polymer composite can be applied to fabricate various devices.
