Abstract: The photocyclodimerization of methyl (or ethyl) 2-naphthoate NA in γ-cyclodextrin aqueous solution was investigated. Spectroscopic analyses reveal that γ-cyclodextrin can encapsulate two molecules of NA to make a stable 2:1 inclusion complex NA@γ-CD in aqueous solutions. Irradiation of NA in the γ-CD aqueous solution results in photocycloaddition with highly selectivity and efficiency,whereas no photocyclodimers could be detected in host-free solution.

Key words: alkyl 2-naphthoate, photocyclodimerization, cubane-like photocyclodimer, γ-cyclodextrin
