Abstract:

A new kind of tailed zinc porphyrin modified by pyridine derivative(o-PyOC6H12OTPPZn) was synthesized and characterized by elementary analysis, UV-Vis, 1H NMR, IR, and MS spectra. The axial coordination reaction was studied between o-PyOC6H12OTPPZn and pyridine derivatives by UV-Vis spectra titration. The binding constants decreased in the order of K(4-MePy)>K(Py)>K(3-MePy)>K(2,4,6-triMePy)>K(2-MePy) for pyridine derivatives. The results show that the capability of axial ligands decreased in the sequence of 4-MePy>Py>3-MePy>2,4,6-triMePy>2-MePy. Moreover, the lowest energy conformations of the complexes between the zinc porphyrin and pyridine derivatives were obtained by simulated annealing and the results explained the experiment results well. The nonlinear optical property of o-PyOC6H12OTPPZn was investigated by Z-scan experiment. Reverse saturated absorption of the compound was observed.
