A short peptide based hydrogel exhibits aqueous insolubility, thixotropy and efficient light induced syneresis. Upon irradiation with UV light, the hydrogel shrinks and expells ∼50% of the solvent. Syneresis is caused by light-triggered trans-cis isomerisation of an azobenzene moiety in the peptide derivative. This expulsion of solvent can be effectively exploited in the removal of low molecular weight contaminants in water.
一种短肽基水凝胶表现出不溶于水、触变性和高效的光诱导相分离。在紫外光照射下，水凝胶收缩并排出约 50%的溶剂。相分离是由肽衍生物中偶氮苯部分的光触发顺反异构化引起的。这种溶剂的排出可以有效地用于去除水中的低分子量污染物。
