| Research Abstract |
Amphiphilic calix[4]resorcinarenes (ampCR) were prepared from resorcinol and aldehydes with alkyl chain under acidic conditions. AmpCR will be a desirable building block of molecular capsules. The ampCR with decyl side chains showed sol-gel transition in diethylene glycol (DEG) by heating and/or cooling solution. The aggregation behavior of ampCR depended on the length of side chain. It was found that the effective encapsulation of ampCR needed a suitable length of alkyl chains. Liquid crystalline cyclodextrins (LCCDs) were prepared by introducing mesogen groups to CDs. LCCD formed a smectic type of thermotropic mesophses with layered regular assembly and orientation. The self-assembly of capsules obtained from LCCDs will be controlled by liquid crystalline structure, depending on the size of CD. The liquid crystalline capsules will achieve regular orientation of molecule involved in the capsule and develop new functional properties such as a quantum effect.
