Electron Transfer Mechanism of Substituted Benzimidazoles: Dimer Switching, Oscillations, and Search for Singlet Fission Properties
Original language description
Reduction and oxidation of 4,7-dimethyl-1,3-dimethoxybenzimidatolium cation (1) and the related dihydroxy analogue (2) were investigated by electrochemical and in, situ spectroelectrochemical methods. Quantum chemical Methods were applied to UV-vis spectra in native, reduced, and: oxidized forms. Compounds were searched for possible formation of a cation radical and a dication radical suitable for the singlet fission effect. Indeed 1 yields by oxidation the target quinoidal structure. However, the reduction step for both compounds' is coupled with. very fast dimerization and prevents obtaining a stable target form. The complex mechanism of the reduction process yields electrochemical current oscillation. Estimation of the maximum Ljapunov exponent proves characteristics of the deterministic chaos.
