Mechanistic study of the photochemical hydroxide ion release from 9-hydroxy-10-methyl-9-phenyl-9,10-dihydroacridine.
The excited-state behavior of 9-hydroxy-10-methyl-9-phenyl-9,10-dihydroacridine and its derivative, 9-methoxy-10-methyl-9-phenyl-9,10-dihydroacridine (AcrOR, R = H, Me), was studied via femtosecond and nanosecond UV-vis transient absorption spectroscopy. The solvent effects on C-O bond cleavage were clearly identified: a fast heterolytic cleavage (τ = 108 ps) was observed in protic solvents, wh...
متن کاملToward organic photohydrides: excited-state behavior of 10-methyl-9-phenyl-9,10-dihydroacridine.
The excited-state hydride release from 10-methyl-9-phenyl-9,10-dihydroacridine (PhAcrH) was investigated using steady-state and time-resolved UV/vis absorption spectroscopy. Upon excitation, PhAcrH is oxidized to the corresponding iminium ion (PhAcr(+)), while the solvent (acetonitrile/water mixture) is reduced (52% of PhAcr(+) and 2.5% of hydrogen is formed). The hydride release occurs from th...

In the crystal structure of the title compound, C(21)H(16)NO(2) (+)·CF(3)SO(3) (-)·H(2)O, the anions and the water mol-ecules are linked by O-H⋯O inter-actions, while the cations form inversion dimers through π-π inter-actions between acridine ring systems. These dimers are linked by C-H⋯O and C-F⋯π inter-actions to adjacent anions, and by C-H⋯π inter-actions to neighboring cations. The water m...

The crystal structure of the title compound, C(21)H(15)N(2)O(4) (+)·CF(3)O(3)S(-), is stabilized by C-H⋯O and C-H⋯F hydrogen bonds, by C-F⋯π, N-O⋯π and S-O⋯π inter-actions, and by O⋯O [2.70 (4) Å] and O⋯F [2.85 (1) or 2.92 (1) Å] contacts; π-π interactions are also present. In the packing of the mol-ecules, acridine units are either parallel or inclined at an angle of 12.5 (1)°. The nitrophenox...

The 12 non-H atoms defining the triple-fused-ring system in the title compound, C(19)H(13)ClN(6), are almost coplanar (r.m.s. deviation = 0.023 Å). The chloro-substituted ring is almost effectively coplanar with the central atoms [dihedral angle = 6.74 (13)°], but the N-bound benzene ring is not [dihedral angle = 54.38 (13)°]. In the crystal, supra-molecular chains along the a axis sustained by...
