Curable polymeric materials and their use for fabricating electronic devices

摘要

Disclosed are curable linear polymers that can be used as active and/or passive organic materials in various electronic, optical, and optoelectronic devices. In some embodiments, the device can include an organic semiconductor layer and a dielectric layer prepared from such curable linear polymers. In some embodiments, the device can include a passivation layer prepared from the linear polymers described herein. The present linear polymers can be solution-processed, then cured thermally (particularly, at relatively low temperatures) and/or photochemically into various thin film materials with desirable properties.

1. A method of fabricating a field-effect transistor having a semiconductor layer comprising a semiconducting electronic material, a dielectric layer comprising an insulating electronic material, and source, drain, and gate electrodes each comprising a conducting electronic material, wherein the field-effect transistor comprises an organic material comprising a ring-opening metathesis polymerization (ROMP) polymer and wherein either the dielectric layer comprises the organic material as the insulating electronic material or the organic material is in contact with at least one of the semiconducting electronic material, the insulating electronic material, and the conducting electronic material, the method comprising:
depositing the semiconducting electronic material to form the semiconductor layer; depositing the ROMP polymer in an organic solvent, wherein the ROMP polymer is a linear polymer characterized by unsaturated bonds in the backbone and is obtained via ring-opening metathesis polymerization from an optionally substituted norbornene monomer, an optionally substituted dicyclopentadiene monomer, or a heteroatom derivative thereof; and annealing the ROMP polymer in an oxygen-containing atmosphere at a temperature between about 110° C. and about 350° C. to provide the organic material.
