title: [The study on the UV and fluorescence properties of PAMAM dendrimers].
abstract: From 0.5 to 5.0 generation PAMAM dendrimers were synthesized with ethylenediamine core by Michael addition reaction and aminolysis reaction two repeated steps. The structure of dendrimers were confirmed by FTIR 1H NMR 13C NMR MS and all of these measurements showed that they were successfully synthesized. Furthermore, The authors studied the UV and fluorescence properties of different generation dendrimers. Because of diffenent terminal groups, it was found that the whole generation and half generation show different ultraviolet absorption peaks and the intensity of ultraviolet absorption is closely related to the molecular skeleton. There is no traditional fluorescence emission groups, but PAMAM dendrimers show the peculiar phenomenon. In this paper we detailedly studied the factors which affect PAMAM dendrimers fluorescence properties.
