| Research Abstract |
Recently, aggregation-induced emission (AIE) fluorophores have attracted attention because of its potential for sensors and EL materials. In this work, we synthesized various polymers, copolymers and gels that having AIE fluorophores based on a AIE monomer consisting of a AIE fluorophore and vinyl group, and investigated their properties and functions. As a result, we find that a polyacrylic acid that carrys an AIE fluorophore in the side chain serves as a fluorescent calcium sensing material that works in extracellar condition ([Ca2+] ~ 2.0 mM). Furthermore, an insoluble crosslinked polyacrylic acid gel also exhibited the calcium sensing property, enabling us to develop a flexible Ca2+ sensing device capable of real- time sensing of Ca2+ concentration.
