title: Temperature-modulated quenching and photoregulated optical switching of poly(N-isopropylacrylamide)/spironaphthoxazine/Rhodamine B hybrid in water.
abstract: Temperature and photo-responsive poly(N-isopropylacrylamide) (PNIPAM)/spironaphthoxazine (WSPO)/Rhodamine B (RhoB) hybrid was studied in this paper. Aqueous PNIPAM/WSPO/RhoB hybrid showed phase transition and fluorescent decrease by rising temperature. And also color and fluorescent change of aqueous PNIPAM/WSPO/RhoB hybrid were showed upon UV/vis light.
