这个帐户描述了一个家庭的磷酸铝，从中性开放框架阴离子框架与迷人的结构体系。与铝硅酸盐沸石相比，这些铝磷酸盐表现出丰富的结构特征，包括超大微孔、混合键合、不同的结构维度、丰富的组成差异以及它们的二维片层的各种堆叠顺序。作为构建单元的低维网络可以通过过渡金属阳离子通过构建过程组装成3-D开放框架。新的化学计量和假设的结构拓扑可以预测和枚举。计算和组合的方法将大大有助于访问的不同结构的范围。
This Account describes a family of aluminophosphates ranging from neutral open-frameworks to anionic frameworks with fascinating structural architectures. In contrast to aluminosilicate zeolites, these aluminophosphates exhibit wealthy structural features, including extra-large micropores, mixed bonding, different structural dimensionalities, rich compositional diversities, and various stacking sequences of their 2-D sheets. The low-dimensional networks, acting as building units, can be assembled to 3-D open-frameworks via transition metal cations through a building-up process. New stoichiometries and hypothetical structural topologies can be predicted and enumerated. Computational and combinatorial approaches will greatly help to access the range of the diverse structures.
