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.
