abstract Two novel coordination polymers (CPs), [Cd 2 (cbta)(phen) 2 (H 2 O)] n (1), {[Zn 2 (cbta)(phen) 2 ] [Zn 2 (cbta) (phen) 2 (H 2 O)]·4H 2 O} n (2) (H 4 cbta = 1-(2-carboxylphenoxy)-2,3,5-benzene tricarboxylic acid; phen = 1,10-phenanthroline), were synthesized and characterized by elemental analyses, FT-IR spectra, single-crystal X-ray diffraction analyses. CP 1 shows a 2D network structure based on tetranuclear CdII clusters and (cbta)4- ligands, which are arranged in a [ABAB···] alternation to form a 3D supramolecular structures through π···π stacking interactions. Noticeably, CP 2 contains two kinds of independent units [Zn 2 (cbta)(phen) 2 ] (A) and [Zn 2 (cbta)(phen) 2 (H 2 O)]·4H 2 O (B) to form a 1D+1D structure. A shows 1D double chain based on Zn1, Zn2, which are recognized each other to generate a 2D supramolecular network (A) by hydrogen bonding interactions. While B are ring chains comprised of Zn3, Zn4, which are linked into 2D supramolecular network (B) through π···π stacking interactions. The peculiar structural feature is that the neighboring 2D networks are arranged in a [ABAB···] alternation to form a 3D supramolecular structure through hydrogen bonding interactions and C H···π and C H⋯O week interactions. Especially the (ctba)4- ligands in 1 – 2 adopt three different conformations and coordination modes. The thermal stabilities, XRD, UV, photoluminescence properties of CPs 1–2 were also studied. Remarkably, CPs 1–2 exhibit photocatalytic activities for degradation of dye (MB) under UV light irradiation and show good stabilities toward UV-light photocatalysis. Graphical abstract Two novel d10 metal CPs have been successfully synthesized and structurally characterized. 1 is a 2D network structure based on tetranuclear CdII clusters. 2 contains two kinds of independent units [Zn2(cbta)(phen)2] (A) and [Zn2(cbta) (phen)2(H2O)]·4H2O (B) to form an 1D+1D structure. The peculiar structural feature is that the neighboring A and B chains are arranged in a [ABAB···] alternation to form 3D supramolecular structure through hydrogen bonding interactions and π ... π stacking interactions. In addition, the thermal stability, photoluminescence and photocatalysis of 1–2 were also studied.

• Two new zn (II) coordination polymers were synthesized and characterized. • Complex 1 and complex 2 can detect 2,4,6-Trinitrophenol (TNP), tetracycline (TET) and fluazinam (FLU) with a high sensitivity and selectivity. • Coordination polymers have shown great potential in clinical diagnosis and treatment. Two new Zn(II) coordination polymers, namely, {[Zn 2 (L)(4,4′-bip) 2 ] ·4H 2 O} n (1) {[Zn (H 2 L) (1,2-die)] · H 2 O} n (2) [H 4 L = 5, 5′-(ethane-1, 2-diyl) diisophthalic acid, 4, 4′-bip = 4, 4′ - bis (1-imidazolyl) biphenyl , 1, 2-die = 1,2-di(pyridin-4-yl)ethene] have been synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffraction, thermogravimetric analysis, IR spectra and fluorescent analysis. Coordination polymers 1 and 2 are 2D network structures. They both have 3D supramolecular structures based on the interspersion of 2D networks. They can detect 2, 4, 6-trinitrophenol (TNP), tetracycline (TET) and fluazinam (FLU) by fluorescence quenching. And the possible reasons for the quenching of TNP, TET, and FLU were discussed in detail, which may be energy resonance transfer. These new zinc coordination polymers could be used multifunctional sensors on NACs, antibiotics and pesticides in the future. In addition, the results of fluorescence sensing experiments show that Zn(II) coordination polymers composed of different auxiliary N donors have significant influence on the detection limits.
