A series of axial di-substituted silicon(IV) phthalocyanines with electron-donating and electron-withdrawing properties were synthesized. The compounds were characterized by elemental analysis, 1H NMR, IR, and ESI-MS. The effect of axialligands on the photophysical properties of siliconphthalocyanines was studied by UV/Vis, steady-state and time-resolved fluorescence spectroscopic analyses. Compared

quenching studies, we have shown silicon phthalocyanines are capable of electron transfer with appropriate substrates, including Hünig’s base. We have also successfully used these catalysts in a reductive quenching reaction where Hünig’s base served as a sacrificial electron donor in the reaction. In addition to being redox-active, our preliminary data also shows these compounds are capable of performing
