Abstract
Poly(m-chloroaniline) (3clp), polydiphenylamine (dpa), copolymer of diphenylamine and m-chloroaniline (3clpdpa), composite of copolymer with TiO
2 (3clpdpat), and composite of copolymer with ZnO (3clpdpaz) have been chemically prepared by oxidative polymerization of polymer and copolymer with TiO
2, ZnO. These were characterized by FTIR, UV–visible, Fluorescence spectra, Atomic force microscopy and TGA. Fluorescence of polymers, copolymer and its composites were aggregation caused quenching type and were concentration dependent. Fluorescence intensity of composites of copolymer was found to be more than the polymer and its copolymer. Multicolor fluorescence was observed in polymers and its copolymer when excited by different laser light. These materials are being used as cell imaging agent.
