ABSTRACT: The polyamidoamine dendrimers, PAMAM-CMAC, was synthesized by decorating PAMAM dendrimer with coumarin-3-methyl acyl chlorine on the periphery. The structures were characterized by FTIR and H-NMR spectra. The fluorescence analysis indicated the PAMAM-CMAC exhibits strong fluorescence emission. The fluorescence intensity of PAMAM-CMAC is much higher than that of PAMAM dendrimer. The fluorescence intensity of PAMAM-CMAC was affected by pH, concentration and solvent. At a considerably big pH value range, the fluorescence emission of PAMAM-CMAC is comparatively stable. Meanwhile, the fluorescence emission of PAMAM-CMAC shifts to longer wavelength with the increase in solvent polarity.
