European Journal of Inorganic Chemistry, Volume 26, Issue 27, September 25, 2023., 2023 Solid‐state dicobalt complexes chemisorb the toxic greenhouse gas nitric oxide (NO) and facilitate its selective transformation in a solvent‐free reaction. In‐crystal dimetallic cooperativity is proposed. Depending on the counter anion present in the solid, a nitrite‐bridged dicobalt(II,III) or dicobalt(III,III) complex is synthesized in this gas‐solid

Influence of Framework n(Si)/n(Al) Ratio on the Nature of Cu Species in Cu‐ZSM‐5 for NH3‐SCR‐DeNOx
ChemCatChem, Volume 14, Issue 18, September 20, 2022., 2022 Copper‐containing zeolite: Changes in the zeolite preparation temperature result in the variation in the framework n(Si)/n(Al) ratio, and thus, the nature of copper species in the Cu‐containing ZSM‐5. Activity and selectivity of catalysts in NH3‐SCR‐DeNOx drop due to the presence of aggregated copper species.

[Ti(fpin)3]2−: a structurally characterized transition metal tris(perfluoropinacolato) complex
Zeitschrift für anorganische und allgemeine Chemie, Volume 647, Issue 18, Page 1815-1818, September 27, 2021., 2021 Abstract The reaction of TiCl3 ⋅ 3THF with perfluoropinacol (H2fpin), triethylamine and silver nitrite in acetonitrile yielded in the formation of the first tris(perfluoropinacolato) complex with a transition metal, (HNEt3)3[TiIV(fpin)3]NO2 (1). The compound was fully characterized with IR and UV‐vis spectroscopy as well as elemental analysis and ...

European Journal of Organic Chemistry, Volume 2020, Issue 22, Page 3171-3191, June 16, 2020., 2020 The use of the heme precursor protoporphyrin IX for biological applications has experienced a steep increase in recent years. Herein, we review possibilities for synthetic modification of this porphyrin scaffold and discuss its emerging key uses in the field of chemical biology. Protoporphyrin IX (PPIX) is the porphyrin scaffold of heme b, a ubiquitous

Seeing the Unseen: The Role of Liquid Crystals in Gas‐Sensing Technologies
Advanced Optical Materials, Volume 8, Issue 11, June 4, 2020., 2020 Liquid crystals are ideal components for real‐time gas sensing platforms due to their stimuli‐responsive nature. Understanding the interaction mechanisms between thermotropic liquid‐crystal sensing systems and gas analytes is crucial for accelerating research innovation and development of novel gas‐sensing platforms.
