  Photophysical and Photochemical Properties of Viologen-Linked N-Alkylporphyrin Diads and Their Metal Complexes

  摘要：

  A new type of viologen-linked or -bridged N-alkylporphyrin and metalloporphyrin diads was synthesized and characterized by H-1 NMR spectroscopy. Although the viologen moiety of free base diads linked with a methylene chain is flexible in solution, the insertion of metal ions results in the extended conformation, where the viologen moiety is located nearly perpendicular to the N-alkylporphyrin plane. The diad, having two porphyrin units bridged by a viologen moiety, is more rigid in conformation than the diad containing one porphyrin unit. The fluorescence quantum yields in the viologen-linked and -bridged N-alkylporphyrins become larger by insertion of H+, Mg2+, Al3+, and Si4+ into the N-alkylporphyrins. This may arise because the extended and orthogonal conformer due to the electrostatic repulsion between the viologen and the central metal ion decelerates the ET quenching of N-alkylporphyrin by the bound viologen unit.

  N-3-Bromopropyl-5,10,15,20-tetraphenylporphyrinato(1-)chlorozinc(II), [Zn(BrPrtpp)Cl], catalyzed the formation of a methylviologen radical cation (MV+•) on steady-state irradiation of degassed methanol solutions with visible light (>420 nm) in the presence of triethanolamine (TEOA). The initial rate (Vi) of the formation of MV+• was of first order in the concentration of MV2+ and in the intensity of
