Abstract

The concept of MOF-in-COF (metal–organic frameworks confined within covalent-organic frameworks) refers to a class of hybrid materials in which MOF structures are confined in a pearl-like chain of unit cells within the 1D channels of 2D COFs. This review summarizes the emergence and recent advances in the development of MOF-in-COF materials, focusing on topics such as the synthesis strategies aimed at achieving specific pore structures and functionalities, particularly in gas separation and ion conduction applications. The tailored pore structure of MOF-in-COF materials imparts two distinctive features: a pore size smaller than that of the basal COF and a modulated internal surface environment within the pores. These unique characteristics enable the synergy of precise molecular sieving and efficient ion transport. Consequently, MOF-in-COFs have been explored as selective gas separation membranes and ion-sieving materials. This perspective article provides an outlook on the future development and potential applications of MOF-in-COF structures, based on their reported properties and current applications.

局限于共价有机框架的金属有机框架：进展与展望。

MOF-in- cof（限制在共价有机框架内的金属有机框架）的概念是指一类MOF结构被限制在二维COFs的一维通道内的珍珠状单元胞链中的杂化材料。本文综述了MOF-in-COF材料的出现和最新进展，重点介绍了以实现特定孔结构和功能为目标的MOF-in-COF材料的合成策略，特别是在气体分离和离子传导方面的应用。MOF-in-COF材料的定制孔结构赋予了两个独特的特征：孔径小于基础COF的孔径和孔内表面环境的调制。这些独特的特性使精确的分子筛分和有效的离子运输协同作用。因此，MOF-in-COFs已被探索作为选择性气体分离膜和离子筛分材料。本文根据MOF-in-COF结构的性质和目前的应用情况，对MOF-in-COF结构的未来发展和应用前景进行了展望。

期刊介绍： Chemistry—An Asian Journal is an international high-impact journal for chemistry in its broadest sense. The journal covers all aspects of chemistry from biochemistry through organic and inorganic chemistry to physical chemistry, including interdisciplinary topics. Chemistry—An Asian Journal publishes Full Papers, Communications, and Focus Reviews. A professional editorial team headed by Dr. Theresa Kueckmann and an Editorial Board (headed by Professor Susumu Kitagawa) ensure the highest quality of the peer-review process, the contents and the production of the journal. Chemistry—An Asian Journal is published on behalf of the Asian Chemical Editorial Society (ACES), an association of numerous Asian chemical societies, and supported by the Gesellschaft Deutscher Chemiker (GDCh, German Chemical Society), ChemPubSoc Europe, and the Federation of Asian Chemical Societies (FACS).
