Disclosed is an opto-electroactive device comprising a metallocene of the formula wherein M is zirconium or hafnium; X is halogen and R<SUP>1</SUP>-R<SUP>5 </SUP>are each independently hydrogen, aryl, alkyl, halogen or -Si(R<SUP>6</SUP>)<SUB>3</SUB>; 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(R<SUP>6</SUP>)<SUB>3</SUB>; or wherein the R<SUP>1 </SUP>substituents on each ring are joined to link the rings in an ansa bridge, and wherein R<SUP>6 </SUP>is 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.
