A robust Zr-MOF (LIFM-28) containing replaceable coordination sites for additional spacer installation has been employed to demonstrate a swing- or multirole strategy for multifunctional MOFs. Through reversible installation/uninstallation of two types of spacers with different lengths and variable functional groups, different tasks can be accomplished using the same parent MOF. An orthogonal optimizing method is applied with seven shorter (L) and six longer (L) spacers to tune the functionalities, achieving multipurpose switches among gas separation, catalysis, click reaction, luminescence, and particularly, ultrahigh methane storage working capacity at 5-80 bar and 298 K.
一种稳定的 Zr-MOF(LIFM-28),其中含有可替换的配位位点,可用于额外的间隔基安装,从而展示多功能 MOF 的摇摆或多角色策略。通过可逆安装/拆卸两种具有不同长度和可变官能团的间隔基,可以使用相同的母体 MOF 完成不同的任务。采用正交优化方法,使用 7 个较短(L)和 6 个较长(L)间隔基来调节功能,实现气体分离、催化、点击反应、发光等多功能开关,特别是在 5-80 巴和 298 K 下具有超高的甲烷存储工作容量。
