摘要
This work reports a SO2 derivative-detecting and colorful hyperbranched polymeric ionic liquid （HBPIL） vesicle through aqueous self-assembly. By a simple anion-exchange, we achieved the combination of functional small-molecule probe of acid fuchsin with HBPILs. The obtained HBPIL vesicle displayed ultraviolet absorption at 544 nm, and was used as a novel SO2 derivative sensor with high sensitivity and visualization. Due to the functional ion pairs enriching on the surface, the SO32 detection limit of the HBPILs vesicles was as low as 0.138 gmol/L, which was about 1.5 orders of magnitude lower than that of acid fuchsin.
