The reduction potential of the methylated pyridine hemiporphyrazine£¨°ë×ϲËຣ© derivative [H2(Me2N2Hp)]I2 shifts to a more positive potential with two reversible waves in the range of -0.4 to -1.2 V compared to the unmodified hemiporphyrazine (H2hp)£¨°ë×ϲËຣ© presenting the reduction potential at -1.19, -1.55, -1.95 and -2.2 V. This is due to the positive charge on the pyridine groups at the periphery of the methylated hemiporphyrazine £¨°ë×ϲËຣ©derivative (H2N2Hp). |
