Charge State Influence on Stability and Isomerism in Dehydrogenated PAHs: Insights from Anthracene, Acridine, and Phenazine

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of

Computational Strategies for Predicting Excited‐State Energies in Eu3+ Down‐Shifting Spectral Converters for Photovoltaic Devices

ChemPhysChem, EarlyView.
A computational strategy to compute the energy of the triplet excited state in europium‐based coordination complexes is presented. This method allows for in silico screening of new systems with can be used as photosensitizers in solar cell‐based technologies.

On the Vapor Pressures, Phase Transitions, and Solid‐State Fluorescence of 2‐(2‐Hydroxyphenyl)benzoxazole and 2‐(2‐Hydroxyphenyl)benzothiazole

ChemPhysChem, EarlyView.
Benzazoles 2‐(2‐hydroxyphenyl)benzothiazole and 2‐(2‐hydroxyphenyl)benzoxazole exhibit tunable optoelectronic properties via excited‐state intramolecular proton transfer. Combining thermogravimetry (TG‐DSC), vapor pressure measurements, and fluorescence spectroscopy, how sulfur (S) versus oxygen (O) substitution dictates their stability, sublimation ...

Electrochemical Water Oxidation Mechanisms Involving Macrocyclic Copper(II) Complexes: Ligand Ring Size Effects on Catalytic Cycles

ChemPhysChem, EarlyView.
The ring size of the ligand strongly influences electronic properties, steric effects, and coordination modes of key intermediates. Both catalysts show similar energy barriers for OO bond formation, but [Cu(12‐TMC)]2+ exhibits more complex mechanisms due to ligand reorganization.
