Thermal Nickel‐Catalyzed N‐Arylation of Sulfonimidamides With (Hetero)aryl Chlorides Enabled by PAd‐DalPhos Ligation

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The nickel‐catalyzed S═NH N‐arylation of sulfonimidamides is described, with useful demonstrated substrate scope involving inexpensive and widely available (hetero)aryl chloride reaction partners, including the active pharmaceutical ingredient chlorpromazine.

Fluorenone and Fluorenemalononitrile‐Tethered Conjugated Microporous Polymers for Efficient CO2 Uptake and Rhodamine B Removal

open access: yesMacromolecular Rapid Communications, EarlyView.
TPET‐F2CN CMP exhibited higher CO2 uptake (2.88 mmol g−1 at 273 K) and superior Rhd B adsorption, with an equilibrium capacity of 98.12 mg g−1 and a maximum monolayer capacity of 155.6 mg g−1. ABSTRACT Herein, two conjugated microporous polymers (CMPs), TPET‐FO and TPET‐F2CN, are functionalized with carbonyl and nitrile groups.

Analytic Expressions for the Isosteric Heat of Adsorption from Adsorption Isotherm Models and 2D SAFT‐VR EoS

open access: yes, 2021
The isosteric heat of adsorption is an important thermodynamic property used to characterise and optimise adsorption processes. In this work, analytic expressions for isosteric heats of adsorption are derived for a collection of commonly used isotherm ...

Interplay Between Oxidation State, Intervalence Charge Transfer Transitions and Electronic Conductivity in a Series of Ru‐Based Metal–Organic Frameworks

open access: yesSmall, EarlyView.
Ru‐based square‐grid metal–organic frameworks undergo dramatic conductivity enhancements after chemical oxidation. The mixed‐valent states exhibit the highest conductivity values, which correlate with the appearance of intervalence charge transfer bands.

Preserving Hierarchical Integrity During Primary Structure Modification of Spherulitic MOFs

open access: yesSmall, EarlyView.
A MOF‐74‐type zinc framework self‐organizes into well‐defined spherulitic superstructures while allowing precise covalent post‐synthetic modification (PSM) of the linkers. A built‐in tetrazine enables fast inverse electron‐demand Diels–Alder (iEDDA) functionalization to uniformly install primary amines.

Determination of isosteric heat of adsorption by quenched solid density functional theory

open access: yes, 2017
The heat of adsorption is one of the most important parameters characterizing energetic heterogeneity of the adsorbent surface. Heats of adsorption are either determined directly by calorimetry or calculated from adsorption isotherms measured at ...
