Orthogonal Ternary Functionalization of a Mesoporous Metal–Organic Framework via Sequential Postsynthetic Ligand Exchange

A sequential postsynthetic ligand exchange process was used to prepare a series of mono-, di-, and trifunctionalized mesoporous metal-organic frameworks (MOFs). Using this process, orthogonal functional groups were installed and thereafter postsynthetically modified with dye and quencher molecules. Microspectrophotometry studies were used to determine the distribution of the two orthogonal functional groups within the MOF crystals.
