Observation of the radical anion intermediates in the photolyses of 4-cyano- and 4-nitro-azobenzene in MTHF at 77 K
Steady-state photolyses of 4-methoxy-4'-cyanoazobenzene and 4-methoxy-4'-nitroazobenzene have been studied in rigid matrices. The radical anions of these azobenzenes have been observed for the first time by the 266 nm and 355 nm light irradiation in 2-methyltetrahydrofuran at 77 K.
