Abstract

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.

Keywords: energy transfer; fluorescence; host-guest systems; in situ encapsulation; metal-organic frameworks.
