2a–2c) with 4′-(substituted-phenyl)-2,2′:6′,2″-terpyridine compounds bearing hydrogen (L1a), p-methyl (L1b), p-phenyl (L1c), p-tolyl (L1d), p-carboxyl (L1e), p-fluoro (L1f), p-hydroxyl (L2a), m-hydroxyl (L2b) or o-hydroxyl (L2c), were prepared and characterized by 1H NMR, IR, elemental analysis and single crystal X-ray diffraction. All the compounds display interesting photoluminescent properties and different
一系列具有4'-(取代的苯基)-2,2':6',2''-叔吡啶化合物的CdCl 2配合物(1a - 1f和2a - 2c),带有氢(L 1a),对甲基(L图1b),p -苯基(大号1C),p -甲苯基(大号1D),p -羧基(大号1E),p -氟(大号1F),p -羟基(大号2A),米-羟基(大号制备了2b)或邻羟基( L 2c),并通过1 H NMR,IR,元素分析和单晶X射线衍射进行了表征。由于取代基的不同,所有化合物均表现出令人感兴趣的光致发光特性和不同的最大发射峰。研究了针对四种人类癌细胞系A549,Bel-7402,Eca-109和MCF-7的体外抗增殖活性,并且细胞活力研究表明这些化合物具有优异的结果,最低IC 50值为0.372( 1c) ,1.003( 1c),1.161( 1b)和0.231( 1c)μM。通过荧光滴定,圆二色光谱和分子建模方法研究了DNA的相互作用。分光
