The title compound, C(17)H(12)ClN, represents a trans isomer with respect to the C=N bond; the dihedral angle between the planes of the naphthyl and benzene groups is 66.53 (5)°.
A simple and efficient fluorescent chemosensor for Al(3+) is reported in the paper. The chemosensor is obtained by dehydration reaction of 2-hydroxy-1-naphthaldehyde and 2-aminophenol. The chemosensor has high selectivity and sensitivity for Al(3+) and displays fluorescence "off-on" switch signal. The detection limit of the chemosensor for Al(3+) can reach… (More)
The asymmetric unit of the title compound, C(20)H(12)Cl(4)N(2)O(2), contains one half-mol-ecule with a center of symmetry along a C⋯C axis of the central benzene ring. The two C=O groups adopt an anti orientation and the two amide groups are twisted away from the central benzene ring by 27.38 (3) and 27.62 (4)°. The mean planes of the dichloro-substituted… (More)
The asymmetric unit of the title compound, C(9)H(11)NO·C(6)H(5)N(3)O(4), contains two independent mol-ecules each of 4-(dimethyl-amino)-benzaldehyde and 2,4-dinitro-aniline. In the crystal, the components are linked by inter-molecular N-H⋯O hydrogen bonds to form one-dimensional chains along [10[Formula: see text]]. Intra-molecular N-H⋯O hydrogen bonds are… (More)
The title compound, C15H17NO4, containing two mol-ecules in the asymmetric unit is a polymorph of the crystal structure published by Martínez et al. [(2011). Eur. J. Org. Chem. pp. 3137-3145] which at 120 K is monoclinic with one mol-ecule in the asymmetric unit. Both mol-ecules in the title compound are in the trans form. In the crystal, N-H⋯O and O-H⋯O… (More)
Curcumin is a widely studied polyphenolic compound which has a variety of biological activity as anti-inflammatory and antitumor drugs. Recent research reported that copper chaperone binding with small molecular may relate to the treatment of cancer. In this work, the interaction between curcumin and CopC has been investigated in detail by means of UV-vis… (More)
There are two independent mol-ecules and one toluene solvent mol-ecule in the asymmetric unit of the title compound, C(25)H(12)Br(4)·0.5C(7)H(8). The dihedral angles between the fluorene ring systems are 85.30 (6) and 84.95 (6)° in the two mol-ecules. The disortions in angles from the ideal sp(3)-hybridization geometry around the tetra-hedral C atoms are… (More)
The title mol-ecule, C(17)H(12)BrN, is in a E conformation with respect to the C=N bond. The dihedral angle between the naphthalene ring system and the benzene ring is 53.26 (3)°.
In the title compound, C(17)H(13)NO, the N-H and C=O bonds are anti with respect to each other. The dihedral angle between the naphthalene ring system and the phenyl ring is 86.63 (5)°. In the crystal, N-H⋯O hydrogen bonds link mol-ecules into chains along .
In the title mol-ecule, C14H13NO2, the dihedral angle between the planes of the benzene rings is 65.18 (4)°. The central amide group has about the same degree of twist with respect to both ring planes, as indicated by the dihedral angles of 34.70 (8) and 30.62 (8)° between its plane and that of the phenyl and 4-meth-oxy-benzene rings, respectively. The C… (More)
