Poly(vinyl cinnamate) (PVA-C) doped with 2,4-dinitroaniline (24DNA) or triphenyl amine (TPA) shows high photoconductivity. Poly[(vinyl cinnamate)-co-(vinyl 3,5-dinitrobenzoate)] (PVA-CD) and poly [ethylene-co-(vinyl cinnamate)-co-(vinyl 3,5-dinitrobenzoate)] (PVA-ECD) are highly photoconductive even in the absence of dopants such as 24DNA.
