  • A porphyrin derivative covalently tinted to Ni aria-macrocycle complex has been prepared. Absorption spectrum of porphyrin-Ni aria-macrocycle dyad (λ$\^$max/$\sub$a/=227 nm) was observed to similar to a sum of those of tetratolylporphyrin (λ$\^$max/$\sub$a/=419 nm) and Ni aza-macrocycle (λ$\^$max/$\sub$a/=227 nm), indicating no electronic interaction between porphyrin and Ni aza-macrocycle moieties. Fluorescence quantum yield of dyad (${\Phi}$$\sub$f/= 0.10) was same to that of tetratolylporphyrin (${\Phi}$$\sub$f/= 0.10). Photoinduced intramolecular electron transfer or energy transfer from excited porphyrin moiety to Ni(II) aza-macrocycle moiety should be very inefficient in dyad.
