摘      要：A new dinucleating 36 membered octoazadiphenol macrocyclic ligand, 3,6,9,12,20,23,26,29 octoaza 35,36 dihydroxy 16,33 dimethyl tricyclo hexatriacontane 1(34),14,16,18(36),31,32 hexene, ODTH, was synthesized by NaBH4 hydrogenation of the corresponding Schiff base obtained from the condensation between triethylenetetraamine and diformyl p cresol. It was characterized by elemental analysis, IR, UV Vis, 1H NMR and MS. The protonation constants of ODTH and the stability constants of its complexes with Cu?in 1∶1 and 1∶2 system(metal ODTH), have been determined potentiometrically at 25.0℃and μ=0.100 mol·L-1 KCl. Potentiometric equilibrium studies indicate that a variety of deprotonated and protonated mononuclear and dinuclear, as well as hydroxy bridged complexes, form in the pH range 2～12 in aqueous solution. The species distributions and the characteristics of ODTH and the complexes are also described.
