Syntheses and properties of PVK modified with perylene structures

A perylene dye monomer, N-(3,5-dimethyl-) phenenyl-Nʹ-allyl-3,4:9,10-perylene tetracarboxylic diimide, was synthesized and copolymerized with N-vinyl carbarzole to produce perylene-modified PVK structures. The monomeric and polymeric dyes were characterized by infrared, absorption, and fluorescence spectroscopies, the results of which indicated little difference between the two forms. Intrinsic viscosity studies revealed that the molecular weights of the polymeric dyes were not very high.
