摘要
Multi-color and white light luminescence materials based on supramolecular assemblies are attractive because of their potential applications in advanced light-emitting material.Herein,a cucurbit[8]urilenhanced lanthanide luminescent supramolecular assembly was constructed in a facile but efficient way using terpyridine imidozalium cations,cucurbit[8]urils and rare earth ions such as Tb3+and Eu3+.Significantly,the resultant fibrous supramolecular assembly,with an average width of 15 nm,could emit remarkable lanthanide luminescence,which was ten times higher than the corresponding terpyridine/Ln3+without cucurbit[8]uril.And the solid state luminescence of supramolecular assembly could be smartly and easily turned among blue,green,red and white by adjusting the molar ratios between Tb3+and Eu3+.The enhanced white-light emission by supramolecular strategy may provide a new approach for smart and tunable solid luminescent materials.
