A series of alumino/galloborates, including (HAPEA)[Al-BO]·12HO (1, APEA = N, N'-bis(3-aminopropyl)ethylenedi-amine), (HDETA)(HDETA)[AlBO] (2, DETA = diethylenetriamine), and (HEDAP)[GaBO]·HO (3, EDAP = N-ethyl-diaminopropane), was solvothermally synthesized and characterized in solid-state by powder X-ray diffraction, Fourier transform infrared spectroscopy, UV-vis spectroscopy, and single-crystal X-ray diffraction. All of them feature the [MBO] (M = Al or Ga) frameworks, charge-balanced by the long chain-like amine cations. Three frameworks exhibit different interlinkage modes of {MBO} layers, resulting in channels varying in size and shape. The flexibility of long chain-like amine cations as well as their significant structure-directing functions in forming these crystalline products is also discussed in detail. Powder second-harmonic generation measurements showed that all three compounds present a nonlinear optical property, and compound 2 exhibits type I phase-matchable optical nonlinearity.
一系列的铝/硼酸根盐，包括 (HAPEA)[Al-BO]·12H2O（1，APEA = N，N'-双（3-氨丙基）乙二胺），(HDETA)(HDETA)[AlBO]（2，DETA = 二乙三胺），和 (HEDAP)[GaBO]·H2O（3，EDAP = N-乙基二氨基丙基），通过溶剂热合成法合成，并通过粉末 X 射线衍射、傅里叶变换红外光谱、紫外可见光谱和单晶 X 射线衍射在固态下进行了表征。它们都具有[MBO]（M = Al 或 Ga）骨架，由长链状胺阳离子平衡电荷。三个骨架表现出不同的{MBO}层的连接模式，导致通道的大小和形状不同。长链状胺阳离子的灵活性以及它们在形成这些结晶产物中的重要结构导向功能也被详细讨论。粉末二次谐波产生测量表明，所有三种化合物都具有非线性光学性质，化合物 2 表现出 I 型相匹配的光学非线性。
