Engineering Halide Perovskites With Chalcogen‐Based Compounds: Insights Into Stability, Interfaces, and Device Integration

open access: yesCarbon Energy, EarlyView.
Chalcogen‐based compounds are explored as versatile tools to enhance the stability and performance of halide perovskites. Their roles in defect passivation, ion migration suppression, and interface engineering are analyzed, along with impacts on device efficiency.

Modular One‐Pot Access to π‐Expanded Tetrakis(Phenothiazinyl)‐Silanes With Broadly Tunable Redox and Emission Properties

open access: yesChemistry – A European Journal, EarlyView.
A library of 21 tetrakis(phenothiazinyl)‐substituted silanes with broadly variable substituent decoration, which are fully reversible multistage redox systems with intense tunable emission from deep blue to yellow–green (441–533 nm), was rapidly synthesized by bromine–lithium exchange/borylation–Suzuki coupling of tetrakis(4‐bromophenyl)silane or by ...

Dioxygen Reduction at a Cu(I) Complex Supported by a Macrocyclic N3O Ligand System

open access: yesChemistry – A European Journal, EarlyView.
A non‐reactive [CuI(14‐TMC)]+ complex is transformed to an efficient catalyst [CuI(14‐TMCO)]+ (TMCO = 4,8,12‐trimethyl‐1‐oxa‐4,8,12‐triazacyclotetradecane) for 4e−/4H+ reduction of O2 by N → O substitution. ABSTRACT CuI(14 TMCO) (1), involving a N3O‐macrocycle, reacts with O2 at cryogenic temperatures to yield an end‐on peroxodicopper(II) species.

PO45 | KHORANA RISK SCORE AND GENOMIC PROFILING FOR PREDICTION OF VENOUS THROMBOEMBOLISM IN OVARIAN CANCER

open access: yesBleeding, Thrombosis and Vascular Biology
Introduction. Ovarian cancer carries a high thromboembolic risk, with VTE incidence up to 13.3%. We conducted a retrospective cohort study to assess Khorana Risk Score (KRS) performance and explore mutational differences between patients with ovarian ...

From Charge‐Transfer Adducts to (Tri)Halide‐Templated Supramolecular Cages: Covalent vs Ionic Products in the Reactions of Pyridin‐4‐ylthio‐Substituted Tetrathiafulvalene With Dihalogens and Interhalogens

open access: yesChemistry – A European Journal, EarlyView.
The reactions between tetra(pyridin‐4‐ylthio)tetrathiafulvalene and Br2/I2/ICl/IBr led to a variety of products, including a rare example of neutral 1:4 CT adduct and ionic products showing supramolecular cage motifs at (tri)halide templates. The nature of the reaction products was elucidated based on XRD analysis, Raman spectroscopy and QTAIM, NCI ...

β‐Ketonitrile‐Modified Prodan Derivatives as Large‐Stokes‐Shift Solvatochromic Fluorophores With Enhanced Brightness and Ratiometric Thermometric Response

open access: yesChemistry – A European Journal, EarlyView.
We report a systematic study of β‐ketonitrile–modified Prodan‐type solvatochromic fluorophores. The β‐ketonitrile substitution induces marked bathochromic shifts in absorption and emission and significantly enhances fluorescence quantum yields in nonpolar solvents.

Tailoring Liquid Crystalline Self‐Assembly and Photophysical Properties of Unsymmetrical Fluorenones via Polar Terminal Groups

open access: yesChemistry – A European Journal, EarlyView.
Novel liquid crystalline fluorenones bearing various head groups were synthesized and characterized. By alteration of the head group, N, SmC, or SmA phases were obtained, and emission properties could be tuned depending on solvent or temperature. ABSTRACT In this work, a series of novel unsymmetrical fluorenone derivatives bearing various head groups ...

Europium Doped Atomically Precise Bismuth Oxido Nanoclusters as Molecular Building Blocks for Photoluminescent Hybrid Materials

open access: yesChemistry – A European Journal, EarlyView.
Europium doping of bismuth oxido nanoclusters (BiO‐NCs) provides stable hosts for Eu3+ in an asymmetric coordination environment, which in turn results in an intense 5D0→7F0 transition and long luminescence lifetimes. Transparent hybrid materials showing characteristic red photoluminescence are accessible via radical copolymerisation of these soluble ...
