A versatile metal-organic framework for carbon dioxide capture and modulating fluorescence properties of Alq3

A versatile three-dimensional four-fold interpenetrated metal-organic framework [Zn5(btz)6(bdc)2(H2O)2]·7DMA (1) has been synthesized under solvothermal condition, which has two types of channels running along a and b axes with dimension of approximately 7.5 × 9 Å2 and 8.5 × 11 Å2. With the appropriate and permanent porosity, compound 1 exhibits high adsorption of CO2 and good capability to encapsulate Alq3 (tris(8-hydro-xyquinoline)aluminum) chromophores to realize tunable fluorescence at solid state. To the best of our knowledge, this material is a rare example of MOFs that exhibit good capability to tune luminescence properties of Alq3.
