ChemInform Abstract: 1,8-Naphthalene-Linked Cofacial Dimeric Phthalocyanines.
Abstract
Reaction of the dihydroisoindole (VI) with (V) (obtained as given in the scheme) leads to the cofacial dinuclear phthalocyanine (VIIIa) (positions of the O-Npe substituents not exactly defined) which on heating with CoCl2 (VII), Cu(OAc)2, or Zn(OAc)2 forms the complexes (VIIIb), (VIIIc), and (VIIId), respectively.
ChemInform Abstract
Reaction of the dihydroisoindole (VI) with (V) (obtained as given in the scheme) leads to the cofacial dinuclear phthalocyanine (VIIIa) (positions of the O-Npe substituents not exactly defined) which on heating with CoCl2 (VII), Cu(OAc)2, or Zn(OAc)2 forms the complexes (VIIIb), (VIIIc), and (VIIId), respectively. (III) and (VIIIa)-(VIIId) are characterized by MS, 1H NMR, IR, and UV-VIS data. Electrochemical and spectroelectrochemical results show unequal behavior of the two phthalocyanine halves of molecule (VIIIb) leading to the mixed-valence form (Ie) on reduction as an intermediate to the fully reduced (If) (only two yields are given).
