Viologen polymers (PV 2 ) with carbon chain spacers were prepared by the polymeric reaction with poly(4vinyl pyridine). These polymers were used as an electrontransfer catalyst (ETC) for the reduction of azobenzene, either in a ZnΒ±PV 2 system (reductant: Zn, in CH 3 CN/ H 2 O) or in a Na 2 S 2 O 4 Β±

## Abstract Several polymers with viologen structure were prepared by polymer analogous reaction with poly(vinyl alcohol) (PVA) and ethylcellulose (EC). The polymers were used as electronβtransfer catalysts (ETC) for the reduction of azobenzene, either in a ZnβPV^2+^ system (reductant: Zn, in CH~3~
## Abstract Liquid crystalline (LC) polymers with monosubstituted ferrocenyl units in the side chain were prepared by radical polymerizations of the corresponding LC and nonβLC acrylates. It was demonstrated that polymerization is useful for the LC orientation and expands the LC temperature range.
