  双核铝配合物的合成，结构和发光研究：包含两个不同配位几何结构的六个配位铝原子的新型结构

  摘要：

  通过使8-羟基喹啉与2-甲氧基乙醇铝和2-乙氧基乙醇铝在回流的苯中反应来制备新型的烷氧基铝双核配合物。这两种化合物，[铝（C 9 H ^ 6 NO）2（μ-OCH 2 CH 2 OR）] 2 [其中R = CH 3（1）和C 2 H ^ 5（2）]，已经通过元素分析和光谱研究。通过单晶X射线分析确定化合物2的分子结构，发现存在离散的不对称二聚体（C 2（对称性）包含两个不同配位几何结构的铝原子，它们通过两个桥连的烷氧基相互连接。化合物1和2的27 Al NMR光谱表明，络合物的固态结构没有保留在溶液中，并且在溶液中形成了四配位的铝原子。两种化合物在被紫外线照射时均显示出发光。比旋光度测量表明，对于两种复合物，溶液中都存在额外的对映异构体（ee）。两种烷氧基铝的羟基喹啉衍生物在普通有机溶剂中均具有良好的溶解性，并具有合适的热稳定性。

  The Modification of Aluminium Tri-sec-butoxide with Different Alcohols and Chelating Ligands: Hydrolysis and Condensation of the Products

  摘要：

  In this work, alcoholysis reactions of aluminium-sec-butoxide, Al(OBu-s)(3), with 2-ethoxyethanol (EtOCH2CH2OH) and 2-butoxyethanol (BuOCH2CH2OH), complexation reactions of Al(OBu-s)(3) and of alcohol-modified Al(OBu-s)(3) with methacrylic acid (MAC) and ethyl acetoacetate (EAAH), and the hydrolysis reactions of Al(OBu-s)(3) and modified Al(OBu-s)(3) are studied in some detail.Alcoholysis reactions of Al(OBu-s)(3) were performed with different mole ratios of 2-ethoxyethanol and 2-butoxyethanol at room temperature and combining ratios were found to be 1:3 [Al(OBu-s)(3):alcohol] by H-1 NMR analyses.Al(OBu-s)(3) and alcohol-modified Al(OBu-s)(3) were reacted at room temperature with equimolar amounts of methacrylic acid and ethyl acetoacetate and the products were characterized by H-1 NMR, GC, FT-IR and elemental analyses.Hydrolysis-condensation reactions of the various compounds thus formed were studied in detail and the products were characterized by gas chromatography, Karl Fisher coulometric titrations, thermal analysis and FT-IR.

  日期：1991.12

  Xerogel with cordierite composition Mg2Al3[AlSi5O18] from aluminium and magnesium 2-ethoxyethoxides and tetraethylortosilicate have been prepared, the latter being not previously partially hydrolized. Conditions to obtain not only homogeneous but also sinterable gel have been determined. All the powders derived were characterized by DTA, TG, BET and X-ray diffraction. Bulk alpha-cordierite material of 97% from theoretical density have been obtained by sintering.
