Abstract

Photolyses of acenaphthylene included in M+ Y zeolites gave the corresponding cis and trans dimers. The ratio of the dimers formed depends on the type of cation present in the supercage. Dimerization is believed to originate from the excited singlet state in the case of lower atomic weight cations and from the triplet state in the case of higher atomic weight cation exchanged zeolites. Dimerization provides insight into the distribution and migration of molecules within the zeolite internal structures.
