Abstract
The photophysical characteristics of a fluorescent PAMAM dendrimer from second generation with sixteen 4-N,N-dimethylaminoethylamino-1,8-naphthalimide units have been studied in organic solvents of different polarity. A positive solvatochromisme and dependence of the fluorescence quantum yield have been observed. The functional characteristics of PAMAM dendrimer in acetonitrile solution in the presence of some metal cations (Zn2+, Ni2+, Pb2+, Mg2+, Mn2+and Ag+) have been investigated. An enhancement in the fluorescence intensity has been observed when Zn2+, Ni2+, Pb2+ and Mg2+ cations are used.
