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)
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)
In the title compound, C(16)H(13)NO(2)S, the C-SO(2)-NH-C torsion angle is -70.1 (2)°. The dihedral angle between the planes of the naphthyl ring system and the phenyl ring is 34.67 (4)°. In the crystal, mol-ecules are linked by inter-molecular N-H⋯O hydrogen bonds into chains along [100]. There are also π-π inter-actions between adjacent naphthyl groups(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)
In the title compound, C(15)H(14)N(4)O(6), the dihedral angle between the aromatic rings is 3.7 (4)°. The nitro groups make dihedral angles of 6.0 (4) and 5.2 (4)° with the parent ring and are oriented at 6.0 (6)° with respect to each other. The meth-oxy groups are inclined at 54.0 (2) and 2.5 (3)° with respect to the benzene ring to which they are(More)
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 [010].
Two 10-hydroxybenzo[h]quinoline metal complexes, bis(10-hydroxybenzo[h]quinolinato) beryllium (Bebq2) and bis(10-hydroxybenzo[h]quinolinato)zincum (Znbq2), have been synthesized. The structure are characterized by 1HNMR, IR and so on. The photophysical processes of Bebq2 and Znbq2 have been carefully investigated by fluorescence spectra. The results show(More)
In this study, a new fluorescent probe 2-(2'-hydroxy-5'-N-maleimide phenyl)-benzothiazole (probe 1), was designed and synthesized by linking the excited state intramolecular proton transfer (ESIPT) fluorophore to the maleimide group for selective detection of thiols in aqueous solution. The fluorescence of probe 1 is strongly quenched by maleimide group(More)
