A 3D terbium-organic framework [TbK(BPDSDC)(DMF) (H2O)(2)](n) (1) with the bifunctional carboxylate-sulfonate ligand of biphenyl-3,3'-disulfonyl-4,4'-dicarboxylate (BPDSDC4-) was synthesized and characterized. The Tb3+ and K+ ions are briged by the carboxylate and sulfonate groups to give a 2D layer, which is linked by the biphenyl moieties to form the 3D pillared framework with the sulfonate groups pointing at the pores. The sulfonate groups on the pores act as the basic sites for the Cr3+ ion sensing by luminescence quenching, highlighting the potential for recognition of Cr3+ ion for compound 1 with the characteristic bright green color.
