Modification of Eu3+–beta-diketonate complex-intercalated LAPONITE® with a terpyridine-functionalized ionic liquid
Abstract
A lanthanide complex-based organic–inorganic hybrid material with intense luminescence has been obtained by modifying Eu3+–beta-diketonate complex-intercalated LAPONITE® with a terpyridine moiety-functionalized ionic liquid. Remarkable luminescence enhancement as well as improved thermal- and photo-stability were observed after modification with the functional ionic liquid. The ionic liquid is believed to coordinate to and sensitize Eu3+ ions as well as decrease proton concentration on LAPONITE® surfaces.
