抄録

When a physical mixture of naphthalene and amorphized 2, 6-di-O-methyl-β-cyclodextrin was heated in a sealed container, a meta-stable complex was crystallized under a mild condition of heating, which showed excimer fluorescence emission of naphthalene. On the other hand, heating of the mixture at high temperature caused the crystallization of stable inclusion complex which showed monomer fluorescence emission.
