Abstract :
BODIPY 558 is an insensitive fluorescent reagent to temperature. But when it is inserted into polydiacetylene (PDA) vesicles, the resultant complex presents a considerable temperature effect. In this article, we reported the temperature-dependent fluorescence intensity of a vesicle-based sensor constructed by PDA and BODIPY fluorescent probe. The fluorescence of BODIPY was considerably quenched in the polymerized diacetylene lipid membrane, but recovered by increasing the temperature of vesicle solution. The mechanism of quenching was detailedly investigated, and we deduced that the fluorescence quenching and recovery were associated with the conjugated conformation of the PDA backbone.
