Claim:
A monomer having the formula (I) wherein X is, identically or differently on each occurrence, CH, CR 1 , or N; Z is, identically or differently on each occurrence, a single chemical bond, a CR 3 R 4 group, a —CR 3 R 4 —CR 3 R 4 — group, a —CR 3 ═CR 4 — group, O, S, N—R 5 , C═O, C═CR 3 R 4 or SiR 3 R 4 ; R 1 is, identically or differently on each occurrence, N(R 5 ) 2 or N(R 5 ) 3 + ; R 2 is, identically or differently on each occurrence, a linear, branched, or cyclic alkyl or alkoxy chain having up to 22 carbon atoms wherein one or more nonadjacent carbon atoms is optionally replaced by N—R 5 , O, S, —CO—O—, or O—CO—O, and wherein one or more H atoms is optionally replaced by fluorine; or is an aryl or aryloxy group having from 5 to 40 carbon atoms and is optionally substituted by one or more nonaromatic radicals R 1 , wherein one or more carbon atoms is optionally replaced by O, S, or N which is; or is CN; R 3 and R 4 are, identically or differently on each occurrence, is H; a linear, branched, or cyclic alkyl chain having up to 22 carbon atoms wherein one or more nonadjacent carbon atoms is optionally replaced by N—R 5 , O, S, —CO—O—, or O—CO—O, and wherein one or more H atoms is optionally replaced by fluorine, or are each an aryl group having from 5 to 40 carbon atoms and is optionally substituted by one or more nonaromatic radicals R 1 , wherein one or more carbon atoms is optionally replaced by O, S, or N; or are each CN; and wherein a plurality of R 3 and/or R 4 optionally define a ring; R 5 is, identically or differently on each occurrence, H; a linear, branched, or cyclic alkyl chain having up to 22 carbon atoms wherein one or more nonadjacent carbon atoms optionally replaced by O, S, —CO—O—, or O—CO—O, and wherein one or more H atoms is optionally replaced by fluorine; or is an aryl group having from 5 to 40 carbon atoms optionally substituted by one or more nonaromatic radicals R 1 , wherein or more carbon atoms is optionally replaced by O, S, or N; m is, identically or differently on each occurrence, 0, 1, 2, or 3; n is, identically or differently on each occurrence, 0, 1, 2, 3, or 4; and Y is, identically or differently on each occurence, bromine and/or boronic acid ester.
