Abstract

Photopolymer-based dielectric materials are provided with methods for preparing the same. Composites and electronic devices including such dielectric materials also are provided.

Claims (28)

1. An electronic device comprising a semiconductor component in contact with a polymeric material, the polymeric material comprising a photocrosslinked product of a random copolymer selected from:

wherein m and n independently are a real number, wherein 0<m<1, 0<n<1, and m +n=1.

2. An electronic device comprising a semiconductor component in contact with a polymeric material, the polymeric material comprising a photocrosslinked product of a random copolymer selected from:

wherein m and n are independently a real number, wherein 0<m≦1, 0<n<1, and m+n=1.

3. The device of claim 1 , wherein the semiconductor component comprises an organic semiconductor compound.

4. The device of claim 1 , wherein the semiconductor component comprises an inorganic semiconductor material.

5. The device of claim 1 , wherein the device is an organic field effect transistor (OFET).

6. The device of claim 5 , wherein the device is selected from a top-contact bottom-gate OFET, a bottom-contact bottom-gate OFET, a bottom-contact top-gate OFET, and a top-contact top-gate OFET.

7. The device of claim 2 , wherein the polymeric material comprises a photocrosslinked product of a homopolymer of the repeating unit:

8. An electronic device comprising a semiconductor component in contact with a polymeric material, wherein the polymeric material comprises a photocrosslinked product of a homopolymer of the repeating units:

9. The device of claim 2 , wherein the polymeric material comprises a photocrosslinked product of a homopolymer of the repeating units:
