From Nanoparticles to Single Crystals of Al‐MOFs: Synergistic Coordination and pH Modulation, and Rapid Sorption Kinetics Assessment by Optical Calorimetry

open access: yesChemistry – A European Journal, Accepted Article.
The properties of metal‐organic frameworks (MOFs), such as sorption kinetics or mechanical and chemical stability, not only depend on their composition and chemical structure, but also on their crystal size and morphology. However, the tunability of the crystallite size of aluminum‐based MOFs (Al‐MOFs) is still a long‐standing challenge. In this study,

Effect of Chalcogen Interaction on the Structure of Methine‐Bridged Trichalcogenophenes

open access: yesChemistry – A European Journal, Accepted Article.
Polythienylenemethylidenes (PTMs) are promising conjugated polymers for organic electronics owing to their narrow bandgaps and extended π‐conjugation. However, their stereochemistry remains unexplored. In this study, methine‐bridged trithiophene and trifuran analogs were synthesized to investigate stereochemistry and chalcogen bonding effects.

Distributed remote antenna unit with selection‐based of (RoF‐IoT) paradigm: Performance improvement

open access: yesIET Communications, EarlyView., 2022
Abstract Mixing the wireless medium with fiber optics can form a new communication system called a radio‐over‐fiber (RoF) network; it is a promising solution that can provide high bandwidth and a reliable connection between numerous sensors in wireless sensor networks (WSN) and the central office (base station) within a particular area.

Synthesis and Reactivity of Triphosphaallyl Cation stabilized by N‐Heterocyclic Carbenes

open access: yesChemistry – A European Journal, Accepted Article.
Reduction of the triphosphaallyl species 6[GaCl4] with GaI[Ga2Cl7] affords the imidazoliumyl‐substituted (L) bicyclo[2.1.1]‐triphosphane, 10[Ga2Cl7], featuring an unprecedented Ga2Cl5‐bridged P3 scaffold. Reactions of 10[Ga2Cl7] with nucleophiles (Cl‐ or NHC) result in rare, selective P–C bond cleavages, affording Ga2Cly‐substituted triphosphiranes ...

Pd[B(S2O7)2]2 and Pd[B(SO4)(S2O7)]2: Two Borosulfates with Pd2+ in Cctahedral and one with Pd2+ in Square Planar Oxygen Coordination

open access: yesChemistry – A European Journal, Accepted Article.
The reaction of elemental palladium with B2O3 and SO3 at elevated temperature results in the formation of blue crystals of Pd[B(S2O7)2]2. Dependent on the reaction conditions, the compound crystallizes in two different polymorphs obtained as bulk samples.
