摘要：

An alpha-cyclodextrin-based size-complementary [3]rotaxane with an alkylene axle was selectively synthesized In one pot via an end-capping reaction with 2-bromophenyl isocyanate In water. Thermal degradation of the [3]rotaxane product yielded not only the original components but also the [2]rotaxane. Thermodynamic studies suggested a stepwise deslippage process.
