Metal complexes of the formulas (I) and (IA), and polymers derived from such complexes are useful in optoelectronic devices: (I) [Formula IA] [Formula XX] Where M is Ir, Co or Rh; Formula XX is a ligand bound to a metal in a cyclic form; R 1 is hydrogen, alkyl, substituted alkyl, aryl, substituted aryl, arylalkyl or substituted arylalkyl; R 2 is hydrogen, alkyl, substituted alkyl, aryl, substituted aryl, arylalkyl or substituted arylalkyl; At least one of R 1 and R 2 is other than hydrogen; R 1a is hydrogen, alkyl, substituted alkyl, aryl, substituted aryl, arylalkyl or substituted arylalkyl; R 2a is hydrogen, alkyl, substituted alkyl, aryl, substituted aryl, arylalkyl or substituted arylalkyl; At least one of R 1a and R 2a is substituted alkyl, substituted aryl or substituted arylalkyl, and at least one substituent of said substituted alkyl, substituted aryl or substituted arylalkyl is a polymerizable group. |
