报道了一种含Sc(DBM)3bath的有机发光二极管(OLED)的界面激基复合物发光,器件结构为ITO/TPD/Sc(DBM)3bath/LiF/Al,其中TPD和Sc(DBM)3bath分别为空穴和电子传输材料。这种电致发光(EL)发射主峰位于597nm,最高亮度接近200cd/m2,这种发射来自于TPD和Sc(DBM)3bath界面处两个功能层的相互作用产生的激基复合物。同时该LED在紫外光照射下还表现出明显的光伏特性。 相似文献

通过水热合成的方法得到了一个新的化合物[Pb2(L1)2(L2)2],并对该化合物进行了元素分析、红外、热重和单晶X-射线表征(H2L1为丁二羧酸阴离子,L2为邻菲啰啉衍生物)。该化合物属于单斜晶系,空间群P21/c,晶胞参数:a=0.795 40(10)nm,b=2.649 0(3)nm,c=1.996 9(2)nm,β=99.784(2)°,V=4.1463(9)nm3,Z=4,R=0.038 0,wR=0.084 5。在该化合物中,丁二酸阴离子连接着铅原子形成一维链状结构。此外,链与链之间的π-π相互作用使一维链形成了三维超分子结构。最后,N-H…29…29O氢键进一步地稳定了此三维超分子结构。 相似文献

The new manganese(Ⅱ) coordination compound, [Mn(Cl)_2(L)_2](1, L = 11-fluorodipyrido[3,2-a:2?,3?-c]phenazine), has been achieved under hydrothermal conditions. The structure of compound 1 was determined by single-crystal X-ray diffraction. 1 crystallizes in monoclinic system, space group C2/c with a = 8.419(2), b = 12.286(2), c = 28.451(6) ?, β = 95.889(3)°, V =2927.5(10) ?~3, Z = 4, C_(36) H_(16) MnF_2 Cl_2 N_8, M_r = 724.41, D_c = 1.644 g/cm~3, F(000) = 1460, μ(Mo Ka)= 0.691 mm~(-1), R = 0.0445 and wR = 0.0982. Adjacent compounds are stacked by one type of π-πinteraction among L ligands to generate a 1D supramolecular chain. Further, the 1D supramolecular chains are stacked by another type of π-π interaction among L ligands to give a 2D supramolecular layer. Moreover, the C-F···π interactions between the carbon atom of the L ligand and the pyrazine ring of the adjacent L ligand further stabilize the supramolecular layer of 1. In addition, natural bond orbital(NBO) analysis has been calculated by the B3LYP/LANL2DZ method, which shows obvious covalent interaction between the coordinated atoms and Mn(Ⅱ) ion. 相似文献

以十二碳醇磷酸酯(DDP)为改性剂, 采用碳化法制备了分散性良好的球状碳酸钙粒子. 通过FESEM, XRD, FTIR及活化度和接触角测试对产物进行了表征. XRD分析结果表明, 随着DDP添加量的增加, 所得CaCO3由方解石型向文石型转变. FTIR结果表明, 改性剂与碳酸钙表面是以化学键合和物理吸附方式相结合. 当DDP含量达到2%时, 接触角为120.43°, 活化度达到99%, 碳酸钙粒子由亲水性转变为完全疏水性. 考察了反应温度和DDP含量对产物形貌与结晶行为的影响, 并对改性机理进行了初步探讨. 将产品填充到聚丙烯(PP)中, 测定了PP的力学性能. 相似文献

The title coordination polymer,[Zn (L) (1,4-BDC)]n (1) (L =2-(4-fluorophenyl)-1H-imidazo [4,5-f] [1,10] phenanthroline and 1,4-H2BDC=1,4-benzenedicarboxylic acid) has been synthesized by hydrothermal method and characterized by elemental analysis,IR and single-crystal X-ray diffraction. It crystallizes in triclinic,space group P1 with a=0.970 85(16) nm,b=1.076 98(18) nm,c=1.203 6(2) nm,α=63.894(2)°,β=69.051(2)°,γ=80.427(2)°,V= 1.055 4(3) nm3,Z=2,C27H15FN4O4Zn,Mr=543.80,Dc=1.711 g·cm-3,F(000)=552,μ(Mo Kα)=1.220 mm-1,R=0.037 2 and wR=0.084 4. The 1,4-BDC ligands linked the Zn(Ⅱ) atoms to form a two-dimensional layer structure. The π-π stacking interactions between L ligands extended the adjacent layers into a three-dimensional supramolecular network. Finally,the N-H…O hydrogen bonds further stabilizes the structure of 1. 相似文献
