triazene (HL) and 1-[(2-carboxymethyl)benzene]-3-[o-aminobenzoic acid]triazene (H2L′), respectively. In the presence of Et3N, the reaction of Pt(PPh3)2Cl2 and HL or H2L′ produces two triazenido platinum(II) complexes, Pt(PPh3)2(L)Cl (1) and Pt(PPh3)2(L′) (2), respectively, which have been characterized by X-ray crystallography, 31P NMR spectra, UV–Vis spectra, emission spectra and cyclic voltammetry
摘要在亚硝酸钠存在下,邻氨基苯甲酸甲酯与2-氨基吡啶或邻氨基苯甲酸反应生成两个三氮烯,即1-[((2-羧甲基)苯] -3- [2-吡啶]三氮烯(HL)和1 -[[(2-羧甲基)苯] -3- [邻氨基苯甲酸]三嗪(H2L')。在Et3N存在下,Pt(PPh3)2Cl2与HL或H2L'的反应产生两个三氮杂ido铂(II)配合物Pt(PPh3)2(L)Cl(1)和Pt(PPh3)2(L') (2)分别通过X射线晶体学,31P NMR光谱,UV-Vis光谱,发射光谱和循环伏安法进行了表征。当在310 nm处激发时,配合物1和2分别在432和442 nm处显示发光,这与最低能量吸收波长1(376 nm)和2(379 nm)的趋势一致。
