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 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)°.
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 this work, the mutant A85M of CopC was obtained. The stability of mutant A85M of CopC and the binding properties of metal ions were clarified through various spectroscopic techniques. The binding capacity of A85M to metal ions was measured by fluorescence spectroscopy and UV differential absorbance. The results suggested that Cu(2+) can bind with A85M in… (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 .
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)
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 title compound, C(10)H(11)NO(4), was synthesized via condensation of 2,3-dimeth-oxy-benzaldehyde with nitro-methane using microwave irradiation without solvent. The H atoms of the -CH=CH- group are in a trans configuration. The dihedral angle between the mean planes of the benzene ring and the nitro-alkenyl group is 23.90 (6)°.
In the title mol-ecule, C(13)H(8)N(4)O(7), the amide fragment has an anti configuration. The mean planes of the two benzene rings form a dihedral angle of 7.78 (4)°. The mean planes of the three nitro groups are twisted by 6.82 (3), 5.01 (4) and 18.94 (7)° with respect to the benzene rings to which they are attached. In the crystal, mol-ecules are linked by… (More)
