Bicyclo[2.2.2]octane-1,4-dicarboxylic acid: towards transparent metal–organic frameworks

Abstract

The preparation of transparent porous materials can offer a different access towards the study of molecules under solid confined space. Metal–organic frameworks represent a unique opportunity due to their tunable pore size, however aromatic linkers present strong absorption and reduce the transparency. Herein, we report the first example of a MOF with bicyclic organic dicarboxylic linkers and its use as a solid solvent.
