Two Silicon Phthalocyanines and a Silicon Naphthalocyanine. Synthesis, Electrochemistry and Electrogenerated Chemiluminescence.
Abstract
The synthesis, spectral characterization, and electrochemical behavior of bis(tri-n-hexylsiloxy)-2,3-phthalocyaninatosilicon (SiPc(OR)2), its dimer (RO(SiPcO)2R), and its naphthalocyanine analog (SiNc(OR)2) are described. All compounds show near UV absorption corresponding to Soret and N bands and intense absorption in the visible-near IR region corresponding to Q-bands. In CH2Cl2, within the solvent stability limit, there are two reductions and one oxidation for SiPc(OR)2 and two reductions and two oxidations for RO(SiPcO)2R and SiNc(OR)2; all appear as reversible one electron waves, although n=2 for the dimer. The difference in the peak potentials of the first oxidation and first reduction waves agrees well with the excitation energy and fluorescence (corresponding to Q-bands) of SiPc(OR)2 and SiNc(OR)2.
