چکیده
In the title compound, C(17)H(14)N(2)O, the dihedral angle between the benzene ring and naphthalene ring system is 11.0 (3)°. The azo group adopts an anti configuration and an intra-molecular N-H⋯O hydrogen bond exists. Mol-ecules are packed by π-π inter-actions between adjacent mol-ecule (closest approach between centroids of benzene and naphthalene rings of 3.501 Å).

The title compound, C(18)H(12)N(2)O, crystallizes in a zwitterionic form. The dihedral angle between the planes of the benzene ring and naphthalene ring system is 13.95 (5)°. An intra-molecular N-H⋯O inter-action results in the formation of a planar six-membered ring, which is oriented at dihedral angles of 13.50 (4) and 4.49 (4)° with respect to the benzene ring and naphthalene ring system, re...

Crystals of the title compound, [Mo(C(14)H(13)NO(2))O(2)(CH(4)O)], were obtained by recrystallization from methanol. The Mo(VI) atom is coordinated by two oxide O atoms and by two O atoms and one N atom of the tridentate 1-[(2-oxidoprop-yl)iminometh-yl]-2-naphtholate Schiff base ligand. The coordination sphere is completed by the O atom of a methanol mol-ecule, yielding a distorted octa-hedron....

The photochemistry of I-naphthol following its electronic excitation in aqueous solution was investigated by a single-photon counting apparatus. It was found that following the proton dissociation the excited naphtholate anion decays non-exponentially withar“* dependence over time. This we attribute to a self-quenching reaction of the naphtholate anion by its geminate proton. The quenching rate...
