Tunability of fluorescent metal–organic frameworks through dynamic spacer installation with multivariate fluorophores

Through dynamic spacer installation, five fluorescent metal–organic frameworks (MOFs) have been constructed based on a proto-MOF LIFM-28 and multivariate ligands as fluorophores. The emissions are tunable via insertion of fluorescent ligands, demonstrating a versatile approach for luminescence tuning by virtue of dynamic spacer installation using swing-role MOFs.
