Abstract
When a physical mixture of naphthalene and amorphized 2,6-di-O-methyl- beta-cyclodextrin was heated in a sealed container, a meta-stable comp lex was crystallized under a mild condition of heating, which showed e xcimer fluorescence emission of naphthalene. On the other hand, heatin g of the mixture at high temperature caused the crystallization of sta ble inclusion complex which showed monomer fluorescence emission.
