The synthesis and electrochemical properties of some novel photosynthesis electron acceptors
Abstract
Arange of dioxathiadiaza heteropentalenes have been prepared and their electrochemical properties have been studied by cyclic voltammetry and e.s.r. spectoscopy. It has been found that these compounds form stable anion radicals in the absence of oxygen and have half-peak reduction potentials in the same range as the bypyridinium compounds such as paraquat (mehyl viologen) or diquat.
