“…Thus, CPs have attracted increasing attention in the recent years. [25][26][27][28][29][30][31] It was found that the adsorption of I 2 by crystalline porous materials, including CPs, was based on noncovalent interactions like halogen bonding interactions between I 2 and Lewis basic sites [32][33][34][35] or charge-transfer interactions between the electron-poor I 2 and π-electron rich aromatics. [36][37][38][39][40][41] Thus, a combination of halogen bond and CT interactions between the guest I 2 molecules and the host frameworks imparts a comprehensive tuning effect on the iodine capture process.…”

“…In comparison, the considered Zn complexes showed more inhibitory potential than Cu ones against S. aureus , while the Cu complexes had more inhibitory effects against P. aeruginosa . [ 72 ] Interestingly, the iodine Cu complex inhibited P. aeruginosa more potently than the chlorine one. Consequently, in addition to the metal ion and organic ligand changing the anions also has a good impact on the antibacterial activity of the complexes.…”

Two new mono‐ and dinuclear zinc (II) complexes with a formula of [Zn (LN)OMeCl] (1) and [Zn2(LN)(N3)2Cl2] (2) [where LN = 1,1,3,3‐tetrakis(3,5‐dimethyl‐1‐pyrazolyl)propane)] have been synthesized in methanol as a solvent and fully characterized by the single crystal X‐ray diffraction, elemental analysis, FT‐IR, UV–Vis, density functional theory (DFT) calculations, antibacterial, and anticancer properties. In both of them, zinc ion is tetrahedrally coordinated to two nitrogen atoms from one of the chelating bidentate bis(3,5‐dimethylpyrazolyl)methane units of the LN ligand and one terminal chlorine. The forth coordination site was occupied by methoxy group in 1 and azide co‐ligand in complex 2. In contrast to 1, in the structure of 2 two metal centers are bridged by the tetradentate chelating LN ligand to form a dinuclear complex. Interestingly, the environment around the central atom in these complexes are mimicked with the core structure of the zinc metalloproteinases, Thermolysin {[NNO]ZnX} and Carbonic anhydrase {[NNN]ZnX} for complexes 1 and 2, respectively. Data analysis of the antibacterial activities demonstrated that the gram positive species showed more sensitivity toward the target title agents. Although, both complexes exhibit antibacterial activities and kill bacteria at low concentration, but complex 1 has higher DNA cleavage activity than 2. Additionally, the cytotoxicity of the free ligand and its complexes was evaluated against the human carcinoma cell line (Caco‐2) by the MTT method and the IC50 values were calculated for all of them. Due to the presence of pyrazole rings in the structure of the ligand and its complexes, these materials have a substantial potential to inhibit cancer cell metastasis. The energetic stabilization due to donor‐acceptor interactions in terms of the natural bond orbital (NBO) analyses and nonlinear optical properties were also examined by using the DFT calculations.

“…Eventually, the Q m of Cu-BCPPy to SD III and DB 38 are calculated to be 557 and 164 mgÁg À1 , respectively, which is higher than many reported copperbased MOF materials (Table 1). [43,[46][47][48][49][50][51][52][53][54][55][56][57] As has been stated above, Cu-BCPPy provides a probability of selectively removing large-size carcinogenic dyes.…”

A novel porous metal–organic framework Cu‐BCPPy based on a desymmetrized heterofunctional ligand 3,5‐di(4‐carboxyphenyl)pyridine has been successfully synthesized under solvothermal conditions. The framework possesses two sizes of 2D straight channels, which are constructed by one pair and three pairs of helixes, respectively. The distortion of the ligand leads to the structure exhibiting a new type of (3,6)‐connected topology. According to the structural characteristic, Cu‐BCPPy can effectively adsorb large carcinogenic organic dyes sudan III (SD III) and direct black 38 (DB 38) but exclude small molecular dyes. Hence, Cu‐BCPPy exhibits effective and selective adsorption performance for the carcinogenic dye DB 38 on the equal proportional mixture dyes methyl orange (MO) and DB 38, fluorescein and DB 38, and basic red 2 (BR 2) and DB 38 with different sizes. In addition, Cu‐BCPPy can be also provided with the characteristic of high iodine adsorption and release, which indicates that it is a promising candidate material for selectively adsorption and separation of many substances.
