PREPARATION OF CONJUGATED AROMATIC/HETEROAROMATIC OLIGOMER-CONTAINING DIELECTRIC POLYMERS AND THEIR APPLICATIONS

摘要

A π-conjugated aromatic/heteroaromatic oligomer-containing vinyl monomer is generally provided, which can include a polymerizable group, a linker group, and a π-conjugated aromatic/heteroaromatic side chain. The π-conjugated aromatic/heteroaromatic side chain includes a first cyclopentadiene ring covalently attached to the linder group, a set of second cyclopentadiene rings covalently attached to the first cyclopentadiene ring, and a third cyclopentadiene ring positioned at a terminal end of the π-conjugated aromatic/heteroaromatic side chain such that the set of second cyclopentadiene rings is positioned between the first cyclopentadiene ring and the third cyclopentadiene ring. Methods are also provided for forming a polymer via polymerizing the π-conjugated aromatic/heteroaromatic oligomer-containing vinyl monomer, and for grafting a π-conjugated aromatic/heteroaromatic oligomer-containing polymer onto a surface of a nanomaterial.

1. A method of forming a polymer, the method comprising:
polymerizing a π-conjugated aromatic/heteroaromatic oligomer-containing vinyl monomer via a controlled/living radical polymerization method, wherein the π-conjugated aromatic/heteroaromatic oligomer-containing vinyl monomer comprises: a polymerizable group, a linker group, and a π-conjugated aromatic/heteroaromatic side chain, and wherein the polymerizable group comprises a vinyl group, and further wherein the π-conjugated aromatic/heteroaromatic side chain comprises: a first cyclopentadiene ring covalently attached to the linder group and having substituted or unsubstituted first hetero-atom substituted therein; a set of second cyclopentadiene rings covalently attached to the first cyclopentadiene ring, wherein the set comprises a number (n) of repeating second cyclopentadiene rings covalently bonded together in a chain, with n being an integer of 1 to about 25, and wherein each of the second cyclopentadiene rings has a substituted or unsubstituted second hetero-atom substituted therein; and a third cyclopentadiene ring positioned at a terminal end of the π-conjugated aromatic/heteroaromatic side chain such that the set of second cyclopentadiene rings is positioned between the first cyclopentadiene ring and the third cyclopentadiene ring, wherein the third cyclopentadiene ring has a substituted or unsubstituted third hetero-atom substituted therein.
