Notes:
Vinylferrocene (M1) has been copolymerized with N-vinylcarbazole (M2) using azobisisobutyronitrile as the initiator. In benzene at 70°C, the reactivity ratios r1 = 0.47 and r2 = 0.20 were obtained. Using an e value of -1.34 for N-vinylcarbazole, the calculated value e for vinylferrocene is about -2.8, in general agreement with the large negative e values vinylferrocene exhibits with other monomers which are electron rich. These copolymers were treated with trinitrofluororenone to give copolymers with carbazole-trinitrofluorenone charge-transfer complex sites (type B). The copolymers were oxidized with dichlorodicyanoquinone to give a series of copolymers with both ferrocenium and ferrocene sites in them (type C). In addition, type C copolymers were further treated with trinitrofluorenone to give a class of polymers having ferrocene, ferrocenium and carbazole-trinitrofluorenone charge-transfer sites (type D). Introducing ferrocene and ferrocenium sites into the poly(vinylcarbazole-trinitrofluorenone) polymers resulted in an increase in their conductivity, but the polymers were no longer photoconducting.
