In this work,a new porous Zr-based metal-organic framework (MOF) with a large Brunner-Emmet-Teller (BET) surface area was prepared by the solvothermal method using 4,4'-(naphthalene-1,4-diyl)dibenzoic acid (NDDA) as the organic ligand,and the luminescent detection performance was studied systematically.The experiments combing with computations indicate that the as-synthesized material can sensitively and selectively detect nitro explosives and metal ions,especially for 2,4,6-trinitrophenol (TNP) and Fe3+,due to the possible electron transfer from inorganic moieties to organic moieties with naphthalene part.Interestingly,owing to its high porosity and large surface area,this Zr-MOF showed quick luminescent response time (in 1 min) for TNP and Fe3+.The results obtained may provide useful information for the design of MOFs with the large permanent porosity in sensing applications for large molecules in the future.
