摘要: Temperature and pH responsive poly(N-isopropylacrylamide) (poly(NIPAM)) copolymer containing D-π-A type pyran-based fluorescent dye (fluorophore) basic comonomer, N-[3-(dimethylamino)propyl]-methacrylamide (DMAPAM) was prepared by free radical polymerization. With increase of values, aqueous poly(NIPAM-co-DMAPAM-co-fluorophore) solution showed decrease a lower critical temperature (LCST) fluorescence intensity, due to change in the ionization state. And also hydrodynamic radius changed correspondingly changes values.
