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

: A new metal-organic framework (MOF), [Zn6 L4 (Me2 NH2+ )4 ⋅3 H2 O] (1) was constructed based on [9, 9'-biscarbazole]-3, 3', 6, 6'-tetracarboxylic acid (H4 L) 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.
