Covalently Linked

A novel visible-light induced electron transfer system composed of the free-base or Zn porphyrin, C60 molecule, and an (L)-lysine was synthesized and characterized. The porphyrin and C60 were covalently linked by the amide bonds through a relatively long and flexible spacer, (L)-lysine. The 1H NMR spectrum of the Zn porphyrin/(L)-lysine/ C60 conjugate (3Zn) suggested that C60 caused the slow molecular motion of this molecule. The steady-state absorption and the emission spectra of 3Zn revealed the intramolecular excited-state electron transfer from the Zn porphyrin moiety to the C60 moiety. The fluorescent lifetime measurement of the excited-state Zn porphyrin in 3Zn indicated the quenching by C60 . The intermolecular electron transfer from the excited-state zinc porphyrin to the viologen derivative in the solution was examined. The Zn porphyrin/(L)-lysine/ C60 conjugate and the free-base porphyrin/(L)-lysine/ C60 conjugate were more effective catalysts than the tetraphenylporphyrin Zn complex, suggesting the intermediacy of the charge separation state, ZnP·+-C60·- .
