In this project, we were investigating about the development of rotaxane-type molecular gels which have a damping effect on their shuttle movement by photoiraadiation. The research was divided as a shuttle ring moiety, a photo-switchable moiety and a polymer moiety. The preparation and structure analyses of the shuttle ring moieties were studied and their photoisomerization and chiral recognition properties were examined. The photochromism of dihydropyrene was investigated as the photo-switching moiety. The grafting polymers were prepared on the silica surface by using "grafting from" and "grafting to" method.

在本课题中，我们研究了轮烷型分子凝胶的开发，该凝胶在光照射下对其穿梭运动有阻尼作用。该研究分为穿梭环部分，光开关部分和聚合物部分。研究了穿梭环基团的制备和结构分析，并对其光异构化和手性识别性能进行了测试。研究了二氢芘作为光开关基团的光致变色性。采用“从接枝”法和“接枝到”法在二氧化硅表面制备了接枝聚合物。
