Two novel salen based chemosensors have been successfully synthesized. UV–vis absorption, fluorescence emission spectroscopy and cyclic voltammetry (CV) were exploited to investigate their recognition toward various metal ions, including Na+, K+, Mg2+, Al3+, Zn2+, Ag+, Pb2+, Co2+, Li+, Ba2+, Ca2+, Cd2+, La3+, Cu2+ and Mn2+ ions. The results indicated that the sensor L1 and L2 exhibited highly selective and sensitive recognition for Zn2+ ions. The binding stoichiometry ratio of L1-Zn2+/L2-Zn2+ were recognized as 4:1 by the method of Job's plot. Meanwhile, this investigation is confirmed by 1H NMR. These results indicated that L1 and L2 can be applied as chemosensor for the detection of Zn2+ ion.

The reactions of triorgano-gallium and -indium etherate with salen ligands in benzene afforded complexes of the type [R2MOC6H4CR′{double bond, long}NCH2-]2, (R/M/R′ = Me/Ga/H (1), Et/Ga/H (2), Me/In/H (3), Et/Ga/Me (4)) in nearly quantitative yields. These complexes have been characterized by elemental analysis, IR, UV-Vis, NMR (1H and 13C{1H}) and mass spectral data. The organogallium complexes showed photoluminescence in blue-green region. The complex, [(Me2Ga)2(O-(C6H4)CH{double bond, long}N-CH2-)2] on recrystallization from benzene-hexane and dichloromethane gave orthorhombic and monoclinic forms, respectively. Both the forms are dimeric with gallium atoms acquiring a distorted tetrahedral configuration defined by two methyl groups, phenolate oxygen and azomethene nitrogen. The complexes [(Me2Ga)2(O-(C6H4)CH{double bond, long}N-CH2-)2] and [(Me2In)2(O-(C6H4)CH{double bond, long}N-CH2-)2] have been employed as alkylating agent for C-C coupling reaction of 1-bromonaphthalene in presence of PdCl2(PPh3)2.

The synthetic protocols for entrapment of transition metal complexes reported here are to expand the diversity in catalysis made possible by the ability of microporous solid to select reactants, transition states, and products based on their molecular size. Herein, we report a synthetic route for the entrapment of transition metal complexes within the nanopores of zeolite-Y. The complexes of transition metals [M = Fe(II), VO(IV)] with Schiff base ligands that are synthesized by simple condensation of 2-hydroxyacetophenone and/or 2-hydroxy-5-chloroacetophenone with ethylenediamine have been entrapped within nanopores of zeolite-Y by flexible ligand method. These materials have been characterized by various physicochemical and spectroscopic techniques such as ICP-OES, FT-IR, 1H and 13C NMR, elemental analyzes, and UV-vis electronic spectral studies, BET, TGA, scanning electron micrographs (SEMs), X-ray diffraction patterns (XRD), conductivity, magnetic susceptibilities as well as AAS. These synthesized catalysts have been utilized as heterogeneous catalysts for liquid phase oxidation of cyclohexene. The reaction parameters have been tuned to optimize higher cyclohexene conversion (%) along with higher selectivity towards the formation of corresponding allylic products. These catalysts were recovered and reused for three times without remarkable loss of activity. Moreover, the intermediate species involved during the catalytic oxidation reaction was synthesized and identified by FTIR and UV-vis spectroscopy.
