CuI-based coordination polymers with 2-thiazolyl sulfide ligands: First examples

Treatment of highly concentrated formaldehyde effluent using adsorption and ultrasonic dissociation on mesoporous copper iodide (CuI) nano-powder

Herein we report a successful degradation of highly concentrated formaldehyde (HCHO, 900 ppm <) effluent from a petrochemical industry using sono-catalytic reaction on highly porous (BET surface of 128 m² g^-1) copper iodide (CuI) nanocrystals as the adsorbent. In this regard, the designed experiments for optimization indicated that the ultrasonic wave (40 kHz) and mass of adsorbent (30 g/L) were significant in HCHO removal so that the combination of the adsorption under ultrasonic degradation resulted in approaching the eliminating efficiency of more than 99%. In this way, GC-MS analysis confirmed the CO₂ production during HCHO degradation. Although the physisorption mechanism (-15.56 kJ/mol) limited the HCHO concentration (~100 ppm) for removal, addition of ultrasonic irradiation significantly improved the process to eliminate 986 ppm of HCHO from the real petrochemical effluent. Moreover, the mechanisms of HCHO decomposition were scrutinized through theoretical studies (density functional theory (DFT)), as well as thermodynamic and kinetics theories. Correspondingly, as calculated from the DFT, the highest adsorption on cleavage plane (111) of the adsorbent was shown to be in complete agreement with its XRD analysis in which the main peak corresponds to the lattice plane (111).

2-(Octadecylsulfanyl)-1,3-thiazole

The title compound crystallizes with a linear alkyl chain bound to the sulfur atom at the 2-position of the thia­zole ring.

The title compound, C₂₁H₃₉NS₂, crystallizes with two mol­ecules in the asymmetric unit, both having a linear 18-carbon alkyl chain bound through a thio­ether group. No π–π stacking or hydrogen bonding is observed. The orientation of the alkyl chains facilitates inter­molecular inter­actions between te chains. The structure is metrically ortho­rhom­bic but crystallizes in the monoclinic space group P2₁ and was found to be twinned by pseudomerohedry (emulating ortho­rhom­bic symmetry) and by inversion. The twin factions refined to 0.37 (4), 0.13 (4), 0.31 (5), and 0.19 (4).

Thiazole- and Thiadiazole-Based Metal–Organic Frameworks and Coordination Polymers for Luminescent Applications

This mini-review focuses on the 2015–2019 literature survey of thiazole- and thiadiazole-containing Metal–Organic Frameworks (MOFs) and Coordination Polymers (CPs) exploited in the applicative field of luminescent sensing.

Chemoselective mechanochemical route toward a bright TADF-emitting CuI-based coordination polymer

We report a simple and effective mechanochemical synthesis of a strongly-emissive TADF-material based on a CuI-coordination polymer that is unobtainable through traditional wet methods.
