A new Li(I)-based metal-organic framework (MOF), namely {(Me2NH2)(2)[Li(NTB)](H2O)(3)(DMF)(2)}(n) (1, NTB = 4.4',4 ''-nitrilotrisbenzoate; DMF = N,N-dimethylformamide), has been successfully achieved by solvothermal reaction of a C-3-symmetric tricarboxytriphenylamine based ligand and Li(I) ion. The resulting framework features a binuclear Li(I) secondary building unit (SBU) and a rare 3.6-connected ant topology. Luminescence properties of 1 towards different metal ions and solvents have also been investigated systematically, with emission intensities significantly quenched towards Fe(III) ion and nitrobenzene (NB). The quenching mechanism has also been investigated in detail.
