摘要：

Continuous and time-resolved fluorescence measurements of l-phenyl-4-[(4-cyano-1-naphthyl)-methylene]piperidine (Fluoroprobe) dissolved in alpha,omega-diacetylpoly(ethylene glycols) (PEGAC's) show that its fluorescence maximum is a sensitive probe of the microenvironment. Morphology changes of the PEGAC's concomitant with increasing molecular weight lead to the onset of fluorescence prior to full relaxation of the surrounding matrix sites.
