The photoswitching of photosensitive bolaamphiphiles based on thymine was investigated. Topochemical principles were applied to create light-responsive supra-amphiphiles by the utilisation of dynamic covalent bonds created by the photo-dimerisation of a DNA base, thymine. In order to induce the photo-dimerisation of thymine, two bolaamphiphilic molecules were designed and synthesised to meet the required
研究了基于胸腺嘧啶的光敏性两亲性苯胺的光开关。拓扑化学原理通过利用DNA碱基胸腺嘧啶的光二聚作用产生的动态共价键,被用于产生光响应性超两亲物。为了诱导胸腺嘧啶的光二聚,设计并合成了两个亲两性分子,以满足所需的[2π+ 2π]光环加成条件。用不同的间隔基合成两亲物,并通过UV / Vis,NMR和红外光谱,流变学,动态光散射和透射电子显微镜研究其光可逆性和形态。
