【 摘 要 】

A vesicle forming polymer, poly(sodium acrylamidoundecanoate) (PSAU) and a water-soluble distyrylbenzene-based fluorophore, TPADSB-C were synthesized and characterized by using UV-vis and photoluminescence(PL) spectroscopy. An inter-chain vesicle formation of PSAU was observed at ~0.01 g/L from N-phenyl naphthylaminefluorescence measurement with changing PSAU concentration in water. Above critical aggregation concentration ofPSAU, optical properties of TPADSB-C were investigated to study the microenvironment modulation through dyeincorporation in the polymeric vesicle. The emission of TPADSB-C in the presence of PSAU vesicles was blue-shiftedand the PL quantum efficiency was increased to 90% due to the microenvironment (e.g. polarity) change in aqueous solution.This study shows that the polymeric vesicle containing molecular fluorophores has a great potential as an efficient,stable and biocompatible labeling tag in biological cell imaging.
