Viscosity effect on the CIDEP of laser photolysis of duroquinone in hydrogen-donor solvents

Viscosity effect on the CIDEP of laser photolysis of duroquinone in hydrogen-donor solvents Chemically induced dynamic electron polarization (CIDEP) is one of the important research fields of dynamic spin chemistry.

Abstract

Chemically induced dynamic electron polarization (CIDEP) is one of the important research fields of dynamic spin chemistry. In the present work, with ethylene glycol, 1,2-propanol and their mixtures with different ratios in volume as solvents and duroquinone as photosensitive molecule, the influence of solvent viscosity on the CIDEP of photolyzed duroquinone radicals has been studied experimentally. In each solvent, duroquinone neutral radicals are observed. Duroquinone neutral radicals are generated through hydrogen transfer reaction from hydrogen-donor solvent molecules to excited duroquinone triplet. The CIDEP mechanism is mainly triplet mechanism. The CIDEP intensity of duroquinone neutral radicals decreases with the increase in the solvent viscosity, and the variation was rapid in low-viscosity range and slow in high-viscosity range.
