Transannular interactions in [2.2] phanes as studied by luminescence and optical detection of magnetic resonance

Abstract

Emission spectra of different types of [2.2] naphthalenophanes were measured at 1.25 K in glasses as well as in small single crystals. In addition, the D and E values of the excited triplet states were studied by optical detection of magnetic resonance in zero field and the results compared with the corresponding monomeres.
