A novel schiff-base fluorescent probe 6,6'-((1E,1'E)-(ethane-1,2-diylbis(azaneylylidene))bis-(methaneylylidene))bis(3-(diethylamino)phenol)(L)was derived from the 2:1 M condensation of 4-(diethylamino)-2-hydroxybenzaldehyde with ethylenediamine and characterized by ^(1)H NMR,^(13)C NMR and FT-IR *** results of spectral analysis showed that the probe L is selective and sensitive to Cu^(2+).The detection limit of L is found to be 19 nmol·L^(-1).There is a good linear relationship between the fluorescence intensity of probe L and the concentration of Cu^(2+)in the range of 0 to 20μmol×L^(-1).X-ray crystal structure of the L-Cu^(2+)complex and the Job plot revealed a 1:1 L-Cu^(2+)identification.

We synthesized one novel schiff-base ligand by modifying the aromatic aldehyde： H2L^1（H2L^1 = N,N？-bis（2-oxy-acetate-3-methoxyl）benzylpropylene（1,3-propane）diamine）. [Ni（C（23）H（24）N2O8）]·6H2O]（1） was prepared by the reaction between H2L^1 and NiCl2·6H2O in C2H5 OH. Compound 1 was structurally characterized by elemental analysis, IR, H NMR and single-crystal X-ray diffraction. 1 crystallizes in monoclinic system, space group P21/n with a = 1.3952（4）, b = 1.3746（9）, c = 1.6121（0） nm, β = 112.66（3）°, V = 2.8533（4） nm^3, Z = 4, Mr = 623.25 and Dc = 1.451 g·cm^（-3）. The Ni（Ⅱ） atom is hexa-coordinated to furnish a slightly distorted octahedral geometry. Lattice water molecules are found in 1, and the H-bonding intersections formed novel water clusters. The IR, antibacterial activity and luminescence of 1 are studied.

A novel, fluorescent probe was synthesized from 2,4-dihydroxybenzaldehyde and 8-hydroxyquinoline for sensing Cu2＋ by the naked eye. The structure was confirmed by 1R, MS, 1H NMR, 13C NMR and the spectral properties of the probe were investigated. It exhibited strong fluorescence responses toward Cu2＋ and high selectivity over other metal ions. The binding constant between the probe and Cu2＋ was calculated using Benesi-Hildebrand equation.
