A new luminescent compound, Zn(8-aminoql)2(SCN)2 (1, 8-aminoql = 8-amino quinoline), has been synthesized and its structure was characterized by IR, elemental analysis and X-ray single-crystal diffraction. Compound 1 belongs to the orthorhombic system, space group Pbca with a = 8.503(2), b = 14.427(4), c = 31.922(8), V = 3916.0(18)3 , Z = 8, C20H16N6S2Zn, Mr = 469.88, D c = 1.594 Mg/m3 , μ = 1.488 mm-1 , F(000) = 1920, T = 296(2) K, the final R = 0.0293 and wR = 0.0645 for all 2763 observed reflections (Ⅰ > 2σ(Ⅰ)). Compound 1 displays a 3D supramolecular architecture formed by N H···S hydrogen bonds and π···π aromatic packing interactions. Photoluminescence studies reveal that it displays obvious fluorescent emission band (λ ex = 320 nm) at 533 nm in the solid state at room temperature. The emission bands possess a broad asymmetric feature, which can be assigned to ligand-to-ligand charge transfer transitions based on DFT calculations.  相似文献

通过异烟肼和4-N,N-二羟乙基苯甲醛来合成一种席夫碱及其锡配合物,并通过核磁、元素分析以及X-射线单晶衍射来进行结构表征。该平面构型的席夫碱采取二齿配位模式,其中的-C=N-在配位后由反式变为顺式。晶体结构数据以及荧光光谱中的显著红移现象表明锡配合物中的π-共轭体系通过配位反应得以延展。体外细胞毒性数据表明,席夫碱配体及其锡配合物对于A-549,MCF-7和Hela等肿瘤细胞的生长抑制活性要强于顺铂。还通过紫外可见光谱及荧光光谱初步研究了两种化合物与DNA的相互作用,结果表明锡配合物可能通过共价结合来导致DNA双螺旋链变形,而席夫碱分子中的氢键效应及其长平面结构可能会阻碍其嵌入DNA双螺旋链。  相似文献
