Synthesis and properties of a novel polyazomethine, the polymer with high photoconductivity and second-order optical nonlinearity

Condensation of N-(3-isopentyl)-3,6-diformylcarbazole and 4-[4-[bis(2-aminoethyl)amino]phenylazo]nitrobenzene gave a new polyazomethine, Cbz1-Azo, which has a good solubility in organic solvents. The polymer possessing carbazole moieties and azo type nonlinear optical chromophores in the polymer backbone showed high photoconductivity and nonlinear optical property.
