Preparation and characterization of luminescent silicone elastomer by thiol-ene 'click' chemistry

摘要

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.
