The intermolecular [2 + 2] photocycloaddition between 3,6-divinylphenanthrene and 4,4'-dimethoxy-3,3'-divinylbiphenyl successfully afforded a [2,2](3,3')biphenylo(3,6)phenanthrenophane possessing a phenanthrene and biphenyl unit. In this compound, the emission from the biphenyl moiety was quenched due to the intramolecular energy transfer to the phenanthrene moiety. Copyright (C) 1996 Elsevier Science Ltd
