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.
