摘　　要：报道了3个具有水溶性的三联吡啶铂-吡啶配合物[Pt(Rtpy)(Spy)](NO_3)_2,Rtpy为2,2′∶6′,2″-三联吡啶衍生物,Spy为(E)-p-N,N-二(正丁基)胺基-4-苯乙烯基吡啶.配合物的合成过程简单便捷,其结构采用核磁、电喷雾质谱以及元素分析法进行了表征.3个配合物在室温水溶液中表现出强荧光发射.在双螺旋的ct-DNA分子以及线型的[Zn(SCN)_3]_n^(n-)阴离子存在下配合物的发光强度显著增强,3个配合物的发射光谱表现出不同变化趋势,与配合物阳离子在聚阴离子上的不同聚集状态有关.Three novel Pt（ Ⅱ ） terpyridine complexes [-Pt（Rtpy） （Spy）3（NO3）2, where the Rtpy stands for the deritivatives of 2,2＇ ： 6＇, 2＂-terpyridine and Spy is （E）-p-N, N-di（n-butyl）amino-4- styrylpyridine, were synthesized through a convenient and efficient method. The structure of the complexes were confirmed by using 1H NMR, ESI-MS and elemental analysis. These water-solu- ble complexes displayed intense fluorescence in H20 solution at 25 ℃, which were enhanced dramatically in the presence of double-helical ct-DNA and linear K,[-Zn（SCN）3]n. The different variation trends in the emission spectra are related to the different aggregation modes of the cations in the Pt（ Ⅱ ） complexes along the polyanions.
