Owing to the discovery of cisplatin, a vast area of use of metallodrugs in cancer treatment was opened, but due to the side effects caused by the cisplatin complexes, researchers...

A piperazine-linked robust N-rich covalent organic polymer (COP), SMCOP-1, was synthesized by a catalyst-free method and characterized by Fourier transform infrared (FTIR), 13 C CP/MAS, X-ray photoelectron spectroscopy (XPS), and powder X-ray diffraction (PXRD). This polymeric material can work as an efficient platform for removing toxic Hg 2+ from wastewater. This system showed >97% Hg 2+ removal, as confirmed by inductively coupled plasma atomic emission spectroscopy (ICP-AES), with a maximum uptake capacity of 1329 mg g −1 . Hg 2+ incorporation inside SMCOP-1 was confirmed by XPS, energydispersive spectrometry (EDS), and elemental mapping of field emission scanning electron microscopy (FE-SEM). The high Hg 2+ removal capacity of SMCOP-1 can be attributed to the strong noncovalent interaction between the Hg 2+ ion and the binding sites of the covalent organic polymer, as suggested by density functional theory (DFT) calculations, noncovalent interaction (NCI) analysis, and the electrostatic potential (ESP) map. The material's recyclability was studied for up to four consecutive cycles, and it was observed that it retained a high removal capacity without any change in the structure and morphology, as confirmed by FTIR and FE-SEM.

Here we report the synthesis of a thermally and chemically robust novel ionic porous organic polymer (iPOP-ANT) with exchangeable Cl- ions by a one-step condensation reaction. The polymer works as...

Here, we report the design and synthesis of a redoxactive multifunctional ionic porous organic polymer iPOP-Bpy with exchangeable Br − ions, incorporating viologen as a redox-active building block. The material shows not only excellent iodine uptake capacity in the vapor phase (540 wt %) but also in the organic (1009.77 mg g −1 ) and aqueous phases (3921.47 mg g −1 ) with very fast adsorption kinetics in all cases. The material also shows its utility in being used as a solid-state NH 3 vapor sensor as it shows very fast color switching in the presence of NH 3 vapor. Furthermore, the material found application as a p-type complementary electrochromic electrode and was fabricated into a bilayer device. Excellent coloration efficiency, high switching speed, and good color contrast were obtained as investigated using bias-dependent optical and spectroelectrochemical studies, paving the way for fabricating power-efficient solid-state electrochromic devices.

In this work four new ruthenium complexes [Ru(η6-p-cymene)(L1)Cl] 1, [Ru(η6-p-cymene)(L2)Cl] 2, [Ru(η6-p-cymene)(L3)Cl] 3 and [Ru(η6-p-cymene)(L4)Cl] 4 [HL1 = (2-cyanophenyl)glycine; HL2 = (5-chloro-2-cyanophenyl)glycine; HL3 = (2-cyano-3-fluorophenyl)glycine; HL4 = (4-cyanophenyl)glycine] were synthesized...
