ABSTRACT:
Disclosed is an opto-electroactive device comprising a metallocene of the formulawherein M is zirconium or hafnium; X is halogen and R1–R5are each independently hydrogen, aryl, alkyl, halogen or —Si(R6)3; or wherein at least two adjacent R substituents on at least one ring are joined to form a fused ring, which may be unsubstituted or substituted with aryl, alkyl, halogen or —Si(R6)3; or wherein the R1substituents on each ring are joined to link the rings in an ansa bridge, and wherein R6is an alkyl group, a substituted alkyl group, an aryl group or a substituted aryl group. Also disclosed is a method for making an opto-electroactive device comprising a metallocene.
