Abstract

Pyrene-fused subphthalocyanine (PySubPc) synthesized from a mixed-condensation reaction of 2,7-di-tert-butyl-4,5,9,10-tetracyanopyrene and tetrafluorophthalonitrile exhibits red-shift of the Q band absorption due to alteration of the electronic structure upon fusion of a pyrene unit. The crystal structure determined by X-ray single crystallographic analysis showed linear arrangement of PySubPc, which was achieved by π-π stacking interactions between the pyrene and subphthalocyanine (SubPc) moieties. Furthermore, the curved conjugation surface of the SubPc moiety and the planar π-conjugation surface of the pyrene moiety enhanced its cocrystallization with C60 molecules. Unique linear arrangement of C60 was observed in the crystal structure of the cocrystallate. Similarly, pyrene-bridged subphthalocyanine dimers can be synthesized from the same precursors, and π-π stacking interactions between these dimers and C60 not only in the solid state but also in solution can be highly expected. In this presentation, we will also report the properties of these subphthalocyanine analogues including their absorption, magnetic circular dichroism (MCD), and fluorescence spectra.
