Abstract
ABSTRACTAs soft materials represent new features that offer long-range orders, they have received considerable interests in optoelectronic fields. In this contribution, the assembly and characterization of soft materials incorporated by lanthanide complex have been reported. The polymeric hosts are derived from polyvinyl alcohol and polyacrylamide-co-polyacrylic acid. As for the metal complexes, the organic chromophore can sensitize europium or terbium ions simultaneously and green/red emissions are achieved. In the aqueous solution phase, the europium complex generates luminescence quenching effect upon the addition of Cu2+ ions and the detection limit has been determined to be 3.6 μM. In addition, the “on–off” changes can be also observed based on the complex-loaded hydrogels and the mechanical properties are discussed. This responsive soft material will demonstrate great potentials in optical devices, biological analysis, and medical diagnosis fields.
