Silver(II) Tetraneopentoxyphthalocyanine and its Redox Chemistry.

摘要

The synthesis and characterisation of the title complex is described . This new silver(II) phthalocyanine is soluble in most organic solvents rendering it suitable for extended study. The complex can be oxidized electrochemically to a silver(III) phthalocyanine which is also indefinitely stable. Further oxidation is possible to the silver(III) phthalocyanine cation radical also showing substantial stability. Reduction to a silver(I) phthalocyanine leads to demetallation on the electrochemical time scale. In support of this electrochemical study, the electrochemistry of metal free tetraneopentoxyphthalocyanine is also reported. Both silver(II) and metal-free tetraneopentoxyphthalocyanine are extensively aggregated in solution. Keywords: Phthalocyanine, Silver, Electrochemistry, Electron spin resonance. (jes)
