Synthesis and characterization of Eu(III) complexes of modified cellulose and poly(N-isopropylacrylamide)

► A series of copolymers of PNIPAM and cellulose were synthesized via ATRP. ► The copolymer had narrow polydispersity indexes and well-defined thermoresponsive. ► Prepared fluorescence complexes by adding a certain amount of europium(III) ion. ► The complexes exhibited a LCST and excellent fluorescence performance.
