A new acylhydrazone-functionalized dual benzimidazole derivative gelator (L) was synthesized. L can self-assemble in DMSO–EG (ethylene glycol) or DMF–water mixtures to form a thermo-responsive supramolecular organogel (L-gel). In order to increase the fluorescence intensity of L-gel (DMSO–EG system), L-gel slowly turned into a clear solution upon addition of one equivalent of RE (rare earth) Y³⁺. Interestingly, this gelator L and Y³⁺ can be assembled into an enhanced blue-light-emitting supramolecular metallogel (Y@gel) in DMF–water mixtures.

稀土Y ³⁺诱导的热响应性超分子凝胶及其发光增强

合成了一种新的酰基hydr官能化双苯并咪唑衍生物胶凝剂（L）。L可以在DMSO-EG（乙二醇）或DMF-水的混合物中自组装，形成热响应性超分子有机凝胶（L-gel）。为了增加L-gel（DMSO-EG系统）的荧光强度，在加入一当量的RE（稀土）Y ^3+后，L-gel逐渐变成澄清溶液。有趣的是，该胶凝剂L和Y ³⁺可以在DMF与水的混合物中组装成增强的发射蓝光的超分子金属凝胶（Y @ gel）。
