Water-soluble poly(aryl ether) dendrimers as a potential fluorescent detergent to form micelles at very low CMC

The self-assembly of amphiphilic pyrene-cored poly(aryl ether) dendrimers has been studied. Pyrene excimer emission at 500nm from the higher generation 6 is observed in KOH aqueous solution at the concentration as low as 1.8 x 10(-5) M, while the excimer emission from lower generation 5 could not be detected at 3.5 x 10(-5) M. The results indicate that the self-aggregation in higher generation dendrimer takes place more efficiently than in lower generation in aqueous solution. (C) 2004 Elsevier Ltd. All rights reserved.
