A New Biscarbazole‐Based Metal–Organic Framework for Efficient Host–Guest Energy Transfer.

A new metal–organic framework (MOF), [Zn6L4(Me2NH2+)4⋅3 H2O] (1) was constructed based on [9, 9′‐biscarbazole]‐3, 3′, 6, 6′‐tetracarboxylic acid (H4L) and Zn2+ ions. The porous framework and intense blue fluorescence of the MOF based on the biscarbazole moiety of the ligand could facilitate efficient host to guest energy transfer, which makes it an ideal platform for the tuning of luminescence. When the MOFs go blue: A metal organic framework (MOF) was constructed based on a novel biscarbazole tetracarboxylic acid ligand. This blue fluorescent MOF serves as an ideal platform for host–guest energy transfer. [ABSTRACT FROM AUTHOR]
