ChemInform Abstract: Matrix Effects in the Reactions of Organic Radical Cations in Ground and Excited States in Solid Phase

Abstract

Effect of matrix physical characteristics on the reactivity and reaction pathways of organic radical cations in ground and excited states in solid phase is considered. The analysis of the results obtained using solid rare gas matrices (argon, krypton, and xenon) showed the ionization potential and polarizability of the matrix to determine to a considerable extent the fate of organic radical cations resulting from charge transfer. In some cases, the matrix control of this kind may lead to nearly complete “switching” between the reaction channels upon changing one inert matrix for another. Data on the mechanism and efficiency of the reactions of electronically excited radical cations in solid phase (freons, sulfur hexafiuoride) were analyzed. It was shown that the matrix effects also had strong influence on the selection of specific reaction pathways and their efficiency in this case
