Comparative Study of Platinum(II) and Platinum(IV) Complexes with 2‐(Pyridin‐2‐ylmethylamino)acetic Acid and 4‐(Pyridin‐2‐ylmethylamino)benzoic Acid: Experimental and Theoretical Analysis

ChemistryEurope, EarlyView.
GA: Ligand precursor 2‐(2‐pyridin‐2‐ylmethylamino)acetic acid (HL1) featuring flexible alkyl chains formed PtII and PtIV complexes with coordination involving the COO‐ group. In contrast, 4‐(2‐pyridin‐2‐ylmethylamino)benzoic acid (HL2) with a rigid p‐phenylene moiety successfully formed the desired PtII and PtIV complexes featuring free carboxylic acid

Crystal structure and Hirshfeld surface analysis of 1-(2,4-dichlorobenzyl)-5-methyl-N-(thiophene-2-sulfonyl)-1H-pyrazole-3-carboxamide

Acta Crystallographica Section E: Crystallographic Communications, 2018
In the title compound, C16H13Cl2N3O3S2, the thiophene ring is disordered in a 0.762 (3):0.238 (3) ratio by an approximate 180° rotation of the ring around the S—C bond linking the ring to the sulfonyl unit.

Poisson-Sigma Models [PDF]

arXiv, 2000
We investigate the Poisson-Sigma model on the classical and quantum level. In the classical analysis we show how this model includes various known two-dimensional field theories. Then we perform the calculation of the path integral in a general gauge, and demonstrate that the derived partition function reduces to the familiar form in the case of 2d ...

From Donor‐Acceptor Ligands to Smart Coordination Polymers: Cyanothiazole‐Cu(I) Complexes for Multifunctional Electronic Devices

Chemistry – A European Journal, EarlyView.
Cyanothiazoles, paired with copper(I) iodide, form complexes with luminescent properties. X‐ray crystallography revealed two types of coordination polymers, while spectroscopic, synchrotron, and electric measurements supported by density functional (DFT) calculations studies highlighted their unique electronic features, offering a foundation for future

Pyrimidine‐Based Four‐Coordinate O^N^O Boron Complexes: Synthesis, Photophysical and Theoretical Studies, and TADF‐Based OLED Devices

Chemistry – A European Journal, Accepted Article.
This article describes the synthesis, along with the full photophysical and computational characterization, of a series of push‐pull boron complexes comprising a sterically‐hindered donor connected to a pyrimidine‐based O^N^O boron chelate. The dimethylacridan‐functionalized fluorophore appears to be the most emissive in the series, both in toluene ...

Bispidine‐Based Copper(II) Coordination Polymers with Remarkable Dynamic Properties, Selective Volatile Organic Compounds Adsorption and Exchange Capabilities

Chemistry – A European Journal, Accepted Article.
This study presents novel Cu(II)‐based bispidine coordination polymers (CPs) with remarkable dynamic properties, volatile organic compounds (VOCs) exchange and selective adsorption capabilities. The coordination requirements of Cu(II) enable, as demonstrated by SC‐XRD and P‐XRD, the formation of either 1D ribbon‐like (1‐TCMSC and 1‐H2OSC) and 2D (1 ...

Intracellular and Extracellular Efficacy of Homoisoflavone Derivatives Against Mycobacterium tuberculosis: Progress Toward Novel Antitubercular Agents

ChemMedChem, Accepted Article.
Tuberculosis (TB) is the leading cause of death among infectious diseases, and new studies focusing new anti‐TB drugs are urgent due to the emergence of drug‐resistant strains. In this regard, homoisoflavones, an underexplored subgroup of flavonoids, were explored for their potential as anti‐TB agents.

A Mechanochemical Route for the Synthesis of Diphenyleneiodonium Salts and the Estimation of Their Relative Solid‐State Reactivities

Chemistry–Methods, EarlyView.
An efficient mechanochemical route for diphenyleneiodonium (DPI) salt synthesis is reported which offers a sustainable and solvent‐free alternative. The solid‐state reactivities of the reported DPI salts were also assessed with the help of morphology predictions and Hirshfeld surface analysis computations to understand the effect of crystal morphology,

Unveiling Correlations in Metal‐Organic Interface Properties: A Computational Exploration of Alternant and Non‐Alternant π‐Electron Systems

ChemPlusChem, EarlyView.
The properties of metal‐organic interfaces are important for the performance of organic electronic devices. The adsorption of alternant and non‐alternant polycyclic conjugated hydrocarbons on Cu(111) was modeled using first‐principle DFT calculations. The difference in interface properties between physisorption and chemisorption is shown and relations ...
