铝基金属有机框架(Al-MOFs)因其主体金属较高的天然丰度,为构筑经济友好的功能材料提供了新途径。然而,由于Al3+的较快的水解动力学,Al-MOFs的结晶过程较为困难,导致相比于其他金属基MOF发展较为缓慢,以Al-MOF为平台的主客体化学研究也因此受限。随着对Al3+水解过程认识的深入,近年来Al-MOFs得到蓬勃发展,对该领域进展进行具有时效性的总结具备重要意义。基于此,本综述详细总结了Al-MOFs的合成方法、结构的多样性以及其在主客体化学方面的应用。在合成方法方面,于传统溶剂热法的基础上加入了对新兴的微波合成法与电化学合成法的介绍,在结构多样性方面则对迄今为止Al-MOFs中所出现过的所有次级结构单元(Secondary building unit, SBU)进行分类总结,从次级构筑单元出发,详细介绍2023年后报道的Al-MOFs结构。此外,本综述针对Al-MOFs的主客体化学应用进行调研,通过对其吸附的客体分子进行分类,归纳了Al-MOFs作为主体吸附客体分子的机理及其作用位点。最后,对Al-MOFs的主客体化学的研究趋势进行了展望。

Due to the high natural abundance of host metal, exploration of aluminum-based metal-organic frameworks (Al-MOFs) provides a new approach to construct economical-friendly functional materials. However, compared with other metal-based MOFs, the fast hydrolysis kinetic of Al3+ leads to great difficulty in crystallization, limiting their investigations in structure and host-guest chemistry. As the understanding towards the hydrolysis of Al3+ deepens, recently the development of Al-MOFs boomed, thus an up-to-date summary of this area is of great importance. Based on this, this review provided a detailed summary of the synthetic methods, structural diversity, and applications in host-guest chemistry of Al-MOFs. Regarding synthetic methods, in addition to the traditional solvothermal method, the emerging microwave-assisted synthesis and electrochemical synthesis were included as well. In terms of structural diversity, all secondary building units (SBUs) reported in Al-MOFs to date are classified and summarized. Starting from these SBUs, the derived Al-MOF structures reported after 2023 were discussed in detail. Moreover, the host-guest chemistry of Al-MOFs was highlighted. By categorizing the guest molecules, this review summarized the corresponding absorption mechanism and binding sites. Finally, this review provided a perspective on the host-guest chemistry of Al-MOFs.
