摘要

Synthesis, electrochemistry and spectroscopic techniques for five zinc(II) coordination complexeswith a combination of tetradentate amines 1,4-bis(3-aminopropyl)piperazine (bapi),triethylenetetramine (tet) and 1,1,4,7,10,10-hexamethyltriethylenetetramine (mtet) and thiodiacetic(tdaH2) or 1,3,5-benzenetricarboxylic acid (btcH3) are described. These complexes of general formulas[Zn2(L)2(tda)](ClO4)2 and [Zn3(L)3(btc)](ClO4)3, where L = bapi, tet, mtet, have been studied inwater solution. Their stability has been studied by electrochemical methods (cyclic voltammetry anddifferential pulse voltammetry) by using the hanging mercury drop electrode. There were also studiedinteractions of zinc(II) complexes with UV radiation assessed by fluorescence spectroscopy. It wasfound out that three complexes (Zn3(bapi)3(btc)](ClO4)3; Zn3(tet)3(btc)](ClO4)3; Zn3(mtet)3( btc)](ClO4)3), after three minutes of UV irradiation became fluorescently active (Em = 400 nm) andfluorescence increased after each interval of UV irradiation.
