摘要：
Pyrene is used as a fluorescence probe to investigate the self-association behavior of poly(sulfate amide)s with various degrees of branching (DB). The ratio of excimer to monomer emission intensity increases gradually wit DB, passes through a critcal point at a DB of about 35%, and then increases dramatically. The study reveals that the higher DB, the stronger the association.
