Abstract:

The electronic absorption and emission spectra of a series of mononuclear and binuclear metal-free phthalocyanine species are reported. The binuclear species are linked through a benzene ring by a bridge of 0,1,2,4 or 5 atoms. The spectroscopic data for the binuclear species, are analysed in terms of exciton coupling between the two halves of the molecule. Intramolecular coupling is seen to depend upon the nature of the bridging link. In some cases a cofacial conformation is possible this gives rise to characteristic long-lived emission near 750 nm. Originator supplied keywords include Electronic Coupling.
