摘要

The electronic absorption spectrum of the hexamethyl(Dewar benzene) radical cation (1~(·+)) is presented for the first time. Partial stabilization of 1~(·+) in organic glasses at cryogenic temperatures is explained in terms of matrix rigidity, which can inhibit the isomerization process. Annealing of the matrix leads to fast isomerization of 1~(·+) to hexamethylbenzene radical cation (2~(·+)) and, at high concentrations of 1, formation of the hexamethylbenzene dimer radical cation can be observed.
