Summary: Two-and tetra-functionalized calix[4]arene derivatives (2-PACX and 4-PACX) with bis(2-picolyl)amine were synthesized and their structures were confirmed by spectroscopic methods. The cation sensing properties of these derivatives were investigated for multiple cations, and 4-PACX was found to be an effective colorimetric sensor for Cu2+ ions. The sensor exhibited a high binding constant and low detection limit in both colorimetric and fluorescent sensing modes.

Summary: In this study, a calix[4]arene-based gelator 1 capable of self-assembling into microspheres in ethanol/H2O mixtures was synthesized. The self-assembly of gelator 1 was found to be driven by cooperative interactions of intermolecular noncovalent forces. Additionally, gelator 1 demonstrated remarkable selectivity towards Hg2+ ions, and the presence of Hg2+ ions enhanced the gelling ability and led to morphological changes of the self-assembled structures through metal-ligand interactions.

Summary: This study presents a novel method to prepare water-dispersible gold nanostructures with near-infrared localized surface plasmon resonance (LSPR) properties. These nanostructures were synthesized using NADH as a reducing agent and an amphiphilic choline-calix[4]arene derivative (CholCalix) forming micelles as a template. Characterization of the CholCalix-Au nanostructures was performed using UV-visible spectrophotometry, Raman spectroscopy, and atomic force microscopy. The agglomeration of the nanostructures due to multiple crosslinking interactions was observed and supported by modeling simulation. The CholCalix-AuNPs demonstrated effective anticancer photothermal-induced effect on human breast cancer cells irradiated with biofriendly light at 808 nm.

Summary: In this study, a series of calixarenes derivatized with 3-phenyl-1H-pyrazole units were synthesized and characterized. These compounds showed specific cytotoxicity for M-HeLa cells with low mutagenicity and haemotoxicity. Compound 7b and 7c induced apoptosis in M-HeLa cells through the mitochondrial pathway and arrested the cell cycle at G0/G1 phase. The overexpression of DNA damage markers in pyrazole-treated M-HeLa cells suggested that calixarene pyrazoles target DNA, which was supported by the interactions between calixarenes and ctDNA at the air-water interface.

Summary: This study synthesized biochar based on sapropel and investigated the effects of chemical modification on its textural characteristics, acid-base properties, and adsorption properties. The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
