Open publisher page 0 citations

Abstract

A dendrimer of PAMAM(1G)-FCD was synthesized.Its structure was characterized via IR,1H NMR,MALDI-TOF-MS,etc.The fluorescent properties of PAMAM(1G)-FCD,as well as the influence of Sn2+ on this dendrimer,were also studied systematically.The results show that the fluorescence of this dendrimer can be significantly enhanced by Sn2+.The UV spectra detected a new absorption peak at 360 nm with the addition of Sn2+ into the solution of PAMAM(1G)-FCD,suggesting that chemical reaction occured in the Sn2+ and PAMAM(1G)-FCD system.This hybrid material of metal-dendrimer holds promise as a scarce material to emit blue fluorescence.
