J. Adamus et al., PHOTOCHEMICAL AND RADIOLYTIC CLEAVAGE OF 10-METHYLACRIDINE DIMER IN SOLUTIONS AND CRYOGENIC GLASSES, Journal of physical organic chemistry, 6(4), 1993, pp. 254-256
10-Methylacridine dimer [(AcrH)2)] dissociates into a pair of 10-methy
lacridyl radicals (AcrH.) on laser excitation (308 nm) in solvents of
various polarities. Exposure of (AcrH)2 in methylcyclohexane glass at
77 K to gamma-rays of Co-60 generates the radical cation (AcrH)2+. The
rmal annealing of the matrix to 90 K results in dissociation of (AcrH)
2+. into AcrH. and 10-methylacridinium cation (AcrH+).
