摘要
Novel luminescent materials that change their emission colors in responding to external stimuli have attracted increasing attentions in the past decades.Herein,we report the preparation of a novel kind of Eu3+-based polymeric organogel with three networks.With dynamic coordination interactions,the organogel shows fast self-healing and adjustable fluorescent emission properties in the presence of different metal ions via coordination interaction competition effect.Dynamic coordination interaction also endows the gel with multiple stimuli-responsive properties such as water,base and acid.The multistimuli responsive fluorochromic organogel demonstrates a new way of preparing optical materials and bio-relevant sensors.
