제목 Colorimetric sensors based on light-responsive polymeric micelle for detection of mercury (II) ions
초록 Polymeric probe with oxime units in the hydrophobic segment of micelle were designed and synthesized for the controlled condition and selective colorimetric sensing of Hg2+ ion in aqueous solutions. In aqueous solution, P1 micellization in water. The key to designing polymeric probe is to construct chromophore and light responsive characteristics of hydrophobic segments. Sensing is not possible in case of micelle type, however the UV-range wavelength (365nm) exposed, change in the hydrophilicity the micelle is dissociation to unimer. In this case selective Hg2+ ion sensing is possible. They exhibited a 80 nm red shift in their maximum absorption upon addition of Hg2+ ions and expose UV light. These polymeric sensor changes color the solution, from pale yellow to pink. These polymeric probes study take advantage of the unique potential platforms for light responsive segment in polymeric micelle with sensing behaviors.
