Claim:
A conjugated or semiconjugated polymer comprising one or more compounds of formula (I), (Ia), (II) or (IIa) wherein: M is Rh or Ir; Y is O, S or Se; Z is B—R 1 , C(R) 2 , —CH═CH—, —CR 1 ═CH—, —CR 1 ═CR 1 —, C═O, NH, NR 1 , PR 1 , P(O)R 1 , P(S)R 1 , O, S, S═O, S(═O) 2 , Se or a C—C single bond; R is, identically or differently on each occurrence, H; F; Cl; NO 2 ; CN; a straight-chain, branched, or cyclic alkyl group having 1 to 20 carbon atoms; a straight-chain, branched, or cyclic alkoxy group having 1 to 20 carbon atoms; wherein one or more non-adjacent CH2 groups of said straight-chain, branched, or cyclic alkyl group or said straight-chain, branched, or cyclic alkoxy group are optionally replaced by —O—, —S—,—NR 1 — or —CONR 2 — and wherein one or more hydrogen atoms of said straight-chain, branched, or cyclic alkyl group or said straight-chain, branched, or cyclic alkoxy group are optionally replaced by F; an aryl group having 4 to 14 carbon atoms optionally substituted by one or more nonaromatic R radicals; or a heteroaryl group having 4 to 14 carbon atoms optionally substituted by one or more nonaromatic R radicals; and wherein a plurality of R substituents, either on the same ring or on the two different rings, together optionally define a further mono- or polycyclic ring system; Ar 1 and Ar 2 are the same or different and are each an aryl or heteroaryl group having from 1 to 40 carbon atoms; Q1 and Q2 are, identically or differently on each occurrence, F; Cl; Br; CN; NO 2 ; a straight-chain, branched or cyclic alkyl group having 1 to 20 carbon atoms; a straight-chain, branched or cyclic alkoxy group having 1 to 20 carbon atoms; wherein one or more nonadjacent CH 2 groups of said straight-chain, branched or cyclic alkyl group or said straight-chain, branched or cyclic alkoxy group are optionally replaced by —O—, —S—, —CO—, —COO—, —O—CO—, —NR 1 —, —(NR 2 R 3 ) + A − or —CONR 4 , and wherein one or more hydrogen atoms of said straight-chain, branched or cyclic alkyl group or said straight-chain, branched or cyclic alkoxy group are optionally replaced by F; an aryl group having 4 to 14 carbon atoms optionally substituted by one or more nonaromatic R radicals; or a heteroaryl group having 4 to 14 carbon atoms optionally substituted by one or more nonaromatic R radicals; A − is a singly charged anion; R 1 ,R 2 ,R 3 and R 4 are the same or different and are each H or an aliphatic or aromatic hydrocarbon radical having from 1 to 20 carbon atoms; a is 0, 1, 2, 3 or 4; b is 0, 1, 2, or 3; c and d are each 0, 1, 2, 3, 4 or 5; e is 0 or 1; n is 1, 2, or 3.
