Preparation and characterization of luminescent silicone elastomer by thiol–ene “click” chemistry

Novel transparent and luminescent silicone elastomers were prepared by thiol–ene chemistry. They show very intense photoluminescence under ultraviolet light and have very high coloric purity. The luminescence was obtained by complexing lanthanide ions into an N-acetyl–L–cysteine functionalized polysiloxane. The functionalized polysiloxane was prepared by an easy thiol–ene reaction and the polysiloxane was cured by thiol–ene reaction to get a crosslinking network. Their structures and properties were characterized thoroughly. The experimental results indicate complexing lanthanide ions reduced the contact angles.
