TECHNOLOGY FOCUS - POLYMERS - Preparation (Disclosed): Preparation of (I) comprises: initiation of polymerization of a metal-containing monomers of formulae (M1b(ER)3) and (M1a(ER)) to give a polymeric compound of formula (M1a(ER)(ER)M1b(ER)2) (representative of (I)).

EXAMPLE - Solid Cu-Se-sec-Bu (1 g) was added to a stirred solution of In(Se-sec-Bu)3 (2.60 g) in benzene (10 ml) under inert atmosphere. The mixture was stirred at 25 degrees C for 12 hours to produce a pale yellow solution. The solvent was removed from the reaction mixture under reduced pressure. The oil was dissolved in pentane and filtered. Solvent was removed from the filtrate under reduced pressure to give polymeric precursor (Cu(Se-sec-Bu)4In) (3.1 g, 86%).
