Excess and deficiency of iron(III) and antibiotics from normal permissible limits will induce serious disorders, so their detection is important but challenging. In this work, the asymmetric amino-functionalized tetra-carboxylate H4L (2′-amino-1,1’:4′,1″-terphenyl-3,3″,5,5″-tetracarboxylic acid) containing large conjugated ter-phenyl aromatic backbones have been synthesized and employed. Through a one-pot powerful solvo-thermal synthetic strategy, a series of unique tri-nuclear cluster-based CaII, MgII and CdII coordination polymers, namely [Ca1.5(μ8-HL)(DMF)]n (1), {[Mg1.5(μ7-HL)·(H2O)2]·3H2O}n (2) and {[Cd1.5(μ10-L)0.75]n·H2O·DMF}n (3) have been successfully prepared. 1–3 exhibit excellent photo-luminescent properties and good fluorescence stability. Structural analyses reveal that tri-nuclear CaII secondary building blocks (SBUS) are linked via HL3?, forming the 2D clustered-based micro-porous coordination polymer 1. As for 2, three carboxylate groups of partly de-pronated HL3? also link these neighboring tri-nuclear MgII SBUS, which constructs the 2D MgII coordination framework 2. As for 3, fully de-pronated L4? also links these neighboring tri-nuclear CdII SBUS, which ultimately constructs the 3D micro-porous coordination framework 3. Experimental powder x-ray diffraction (PXRD) patterns coincide well with the theoretical patterns, which indicate that we have successfully synthesized the pure phase material 1–3. Photo-luminescent experiments demonstrate that coordination polymers 1–3 can be successfully applied towards bi-functional sensing for sensitive detection of Fe3+ and the antibiotics NZF (Nitrofurazone). To the best of our knowledge, this is the first example of the application of amino-functionalized tri-phenyl tetra-carboxylate based MOFs towards bi-functional discrimination of Fe3+ and NZF antibiotics with high efficiency Ksv values (For Fe3+: 7.28 × 104 M?1 for 1; 3.38 × 104 M?1 for 2 and 3.29 × 104 M?1 for 3 and for NZF antibiotics: 4.47 × 103 M?1 for 1; 4 × 103 M?1 for 2 and 5.6 × 103 M?1 for 3).
