Synthesis And Characterization Of Some Chiral Aminophenol Derivatives And Several Novel Tetrazole Coordination Complex

Basing on using chiral organic ligand as building block to self-assemble chiral metal organic coordination polymers with metal ion, several unreported aminophenol derivatives with cyanogens and ethylene were synthesized by L-tyrosine, dihydroxyphenylalanine (DOPA), aspartic acid and glutamic acid.Through the way of hydroponic reaction, we gained two crystal structures of 2-(1H- tetrazol-5-yl)benzonitrile and 4-((2H-tetrazol-2-yl)methyl)benzonitrile with tetrazolyl and cyanogen group. Through the way of hydrothermal reaction, we gained two tetrazole metal coordination compounds (1, 2) with the ligand 2-(1H-tetrazol-5-yl)benzoic acid and three tetrazole metal coordination compounds (3, 4 and 5) with the ligand 5-(1H-tetrazol-5-yl) isophthalic acid using the coordination ability of the N atoms in tetrazole and the O atoms in carboxyl. Compound 1: C2 / c, a = 1.9886 (4) nm; b = 0.7352 (15) nm; c = 1.5409 (3) nm;β= 115.97 (3) o; compound 2: C2, a = 1.9696 (8) nm; b = 0.7134 (18) nm; c = 1.4932 (6) nm;β= 114.39 (2) o; compound 3: P-1, a = 0.7909 (16) nm; b = 0.8448 (17) nm; c = 1.0994 (2) nm;α= 102.65 (3) o;β= 124.319 (17) o;γ= 96.28 (3) o; compound 4: P21 / c, a = 0.8020 (24) nm; b = 1.0358 (25) nm; c = 1.7901 (41) nm;β= 92.422 (18) o; compound 5: C2 / c, a = 1.9593 (9) nm; b = 1.1034 (17) nm; c = 1.3330 (6) nm;β= 124.319 (17) o. We also tested the fluorescent and ultraviolet characters of the two compounds 3 and 4. Enhanced luminescence efficiency and slightly blue shift of the absorption peaks in ultraviolet spectrum of the lanthanon coordination compounds were obvious contrast to the original tetrazolyl ligands.Structures of the productions were characterized by IR spectroscopy, UV spectroscopy, elemental analyses, mass spectrum, fluorescent spectroscopy, 1H NMR spectroscopy and X-ray single crystal diffraction.
