Abstract

Disclosed are low-temperature thermally and/or ultraviolet light curable 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 low-temperature thermally and/or ultraviolet light curable polymers. In some embodiments, the device can include a passivation layer prepared from the low-temperature thermally and/or ultraviolet light curable polymers described herein. In certain embodiments, a polymer of the disclosure has a repeating unit having the structure (I) in which Q1-Q2 and Q3-Q4 are each independently —C(H)═C(H)— or (II) in which each n is independently selected from 1, 2, 3 and 4, and the polymer includes at least one repeating unit of Formula (I) wherein Q1-Q2 and Q3-Q4 is (II).

A polymer having a repeating unit of Formula (I):

wherein in each repeating unit
X is independently selected from the group consisting of —CH2—, —CHR—, —CR2—, —C(O), —SiH2—, —SiHR—, —SiR2—, —NH—, —NR—, —O— and —S—;
Y is independently absent or selected from the group consisting of —CH2—, —CHR—, —CR2—, —C(O), —SiH2—, —SiHR—, —SiR2—, —NH—, —NR—, —O— and —S—;
R is independently selected from the group consisting of a halogen, —OR3, —C(O)OR3, —OC(O)R3, —NR4R5, —C(O)NR4R5, —OC(O)NR4R5, a C1-10alkyl group, a C1-10haloalkyl group, and an optionally substituted aryl or heteroaryl group, wherein R3 is a C1-10alkyl group or a —Si(C1-10alkyl)3 group, and R4 and R5 independently are hydrogen or a C1-10alkyl group;
and
m is independently 0, 1 or 2,
Q1-Q2 and Q3-Q4 are each independently —C(H)═C(H)— or
in which each n is independently 1 or 2,
provided that the polymer includes at least one repeating unit of Formula (I) wherein Q1--Q2 or Q3-Q4 is
