The binding of fluorescent probe molecules to
poly(amidoamine) starburst dendrimers of generations
G-0, G-1, and G-2 was investigated. The solubilizing capability of
these new materials, in aqueous media,
increases with increasing degree of their generation. Pyrene
fluorescence however undergoes significant
quenching in the solubilized state. In the higher generations, G-1
and G-2, excimer fluorescence was
observed even at [pyrene]/[dendrimer] ratios as low as
10-3.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
