Abstract
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.
摘要
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。
