Three new aluminoborates (ABOs) KCs[Al{BO(OH)}{BO(OH)} (1), KCs[Al{BO}{BO(OH)}] (2), and Cs[Al{BO}{BO(OH)}] (3) have been made under solvothermal conditions. 1 features a 1D tube constructed by the alternation of [BO(OH)] clusters and AlO units, onto which the [BO(OH)] triangles are grafted. To further construct higher dimensional structures based on the structure 1, solvents were adjusted for high basicity, resulting in the formations of the 3D ABO frameworks 2 and 3. 2 and 3 are isostructural and built from [BO] clusters, AlO tetrahedra and [BO(OH)] triangles, in which [BO] clusters are bridged by AlO tetrahedra to produce a 2D ABO layer with 14-membered ring (MR) windows, and the [BO(OH)] triangles act as the linkers to bridge the adjacent ABO layers to form 3D ABO frameworks containing eight types of channels. UV-vis diffuse reflectance spectra indicate that 1, 2, and 3 have potential applications in deep ultraviolet (DUV) regions.
在溶剂热条件下制备了三种新型铝硼酸盐（ABO）：KCs[Al{BO(OH)}{BO(OH)}]（1）、KCs[Al{BO}{BO(OH)}]（2）和Cs[Al{BO}{BO(OH)}]（3）。1具有由[BO(OH)]簇和AlO单元交替构成的一维管，[BO(OH)]三角形接枝在该管上。为了基于结构1进一步构建更高维度的结构，对溶剂进行了高碱性调节，从而形成了三维ABO框架2和3。2和3是同构的，由[BO]簇、AlO四面体和[BO(OH)]三角形构成，其中[BO]簇由AlO四面体桥连以产生具有14元环（MR）窗口的二维ABO层，[BO(OH)]三角形作为连接体桥连相邻的ABO层以形成包含八种类型通道的三维ABO框架。紫外可见漫反射光谱表明，1、2和3在深紫外（DUV）区域具有潜在应用。
