制备了两亲配体N-十六烷基-8-羟基-2-喹啉甲酸胺(HL)十个配合物的LB膜.采用π-A等温线和小角X射线衍射等方法研究了这些LB膜的性质和结构.两亲配合物的单分子占有面积为(1.25±0.06)nm~2和(0.74±0.06)nm~2,分别对应于两亲分子中两个喹啉环平躺和环与环之间以一定的角度倾斜于气/水界面.LB膜内分子排列是二维有序的超晶格结构,双层高度(5.0±0.1)nm;LB膜具有导电各向异性,其平面和垂直直流电导率分别为10~(-5)S·m~(-1)和10~(-9)S·m~(-1);LB膜的高荧光性质使之可以用作为电致发光器件的发光材料.以LaL_2(H_2O)_4Cl的LB膜为发光层的单层电致发光器件的驱动电压为9V,发光亮度330cd/m~2,为黄绿色发光.
The LB films of ten complexes of amphiphilic ligand N-hexadecyl-8-hydroxy-2-quinolinecarboxylate (HL) were prepared.The π-A isotherms and small angle X-ray diffraction LB film properties and structure of the amphiphilic complexes occupy a single molecule area of (1.25 ± 0.06) nm ~ 2 and (0.74 ± 0.06) nm ~ 2, corresponding to the amphiphilic molecules in the two quinoline ring lying and The angle between the ring and the ring is inclined to the gas / water interface at an angle. The molecular arrangement in the LB film is a two-dimensional ordered superlattice structure with a bilayer height of 5.0 ± 0.1 nm. The LB film has conductivity anisotropy, The planar and vertical DC conductivities are 10 -5 S m -1 and 10 -9 S m -1, respectively. The high fluorescence of LB films makes it possible to use The luminescent material of electroluminescent device The driving voltage of monolayer electroluminescent device with LB film of LaL_2 (H_2O) _4Cl as luminescent layer was 9V, the luminescence brightness was 330cd / m ~ 2, which was yellow-green luminescence.
