Fluorescence Enhancement of the Water- Soluble Poly{1,4-phenylene-[9,9-bis- (4-phenoxybutylsulfonate)]fluorene-2,7-diyl} Copolymer in n-Dodecylpentaoxyethylene Glycol Ether Micelles (original) (raw)

AI-generated Abstract

This research explores the fluorescence properties of a water-soluble copolymer, poly{1,4-phenylene-[9,9-bis(4-phenoxybutylsulfonate)]fluorene-2,7-diyl} (PBS-PFP), in the presence of the nonionic surfactant n-dodecylpentaoxyethylene glycol ether (C12E5). The addition of C12E5 leads to significant increases in fluorescence intensity and blue shifts in absorption and emission peaks. Furthermore, the study provides insights into the molecular interactions within micelles formed by C12E5 and their implications for the stabilization of the polymer in aqueous solutions, indicating potential applications in chemical and biological sensing.
