The active layer is a photoactive layer. The active layer further comprises a photoactive material.b = 0-4;c = 0-1;d = 0-2; ande = 0-3. Preferred Definitions:    Ar1 = single bond, phenylene, p-biphenylene, p-terphenylene, naphthylene, phenylenenaphthylene, or naphthylenephenylene;    Ar2 = naphthyl or substituted phenyl moiety of formula (IV) (where crosslinking substituents are present on at least one Ar2);    R3 = alkyl, alkoxy, siloxane or silyl;    f = 0-4;    g = 0-5;    m = 1-6;    Ar3 = substituted phenyl moiety of formula (III);    R1, R2 = 1-12C alkyl or 1-12C alkoxy;    x = 0.4; and    M = aromatic group having triarylamine units or an aromatic group having a crosslinkable substituent.    EXAMPLE - All operations were carried out in a nitrogen purged glovebox. N7,N7'-bis(3-bromophenyl)-2,2'-dimethyl-N7,N7'-bis(3-octylphenyl)-1,1'-binaphthyl-7,7'-diamine (1.036 g) was added to a scintillation vial and dissolved in toluene (22 ml). A clean, dry 50 ml Schlenk tube was charged with bis(1,5-cyclooctadiene)nickel(0) (0.500 g). 2,2'-Dipyridyl (0.284 g) and 1,5-cyclooctadiene (0.197 g) were weighed into a scintillation vial and dissolved in N,N'-dimethylformamide (5.5 ml). The solution was added to the Schlenk tube. The Schlenk tube was inserted into an aluminum block and the block was heated and stirred on a hotplate/stirrer at a setpoint that resulted in an internal temperature of 60 degrees C. The catalyst system was held at 60 degrees C for 30 minutes and then raised to 70 degrees C. The monomer solution in toluene was added to the Schlenk tube and the tube was sealed. The polymerization mixture was stirred at 70 degrees C for 18 hours. After 18 hours, the Schlenk tube was removed from the block and allowed to cool. The tube was removed from the glovebox, the contents were poured into a solution of concentrated hydrochloric acid/methanol (1.5% vol./vol.), stirred for 2 hours and worked up, to give a poly(N7,N7'-bis(3-bromophenyl)-2,2'-dimethyl-N7,N7'-bis(3-octylphenyl)-1,1'-binaphthyl-7,7'-diamine) of formula (Ia) (84.6%).
