A Flexible Cu-MOF as Crystalline Sponge for Guests Determination

A trifluoromethyl functionalized linker and Cu-O chain composed MOF, LIFM-100, was used as “crystalline sponge” to determine eight hardly crystallized liquids’ configurations based on its flexibility conformation, suitable pore size, electron-rich channel environment, and low symmetric space group. The H bond interactions between host–guest and guest–guest were well analyzed.
