Transition Metal Compounds as Thermochromic Materials: Classification, Properties, Limitations, and Applications

open access: yesEcoEnergy, EarlyView.
This review systematically examines how different transition metal compounds—such as binary and multinary metal oxides, halides, sulfides, and salts—exhibit thermochromism based on the d‐electron configurations of their transition metal cations. It focuses on three main mechanisms of thermochromism: phase transition, charge transfer, and bandgap change.

Light‐Induced Structural Reorganization of Fe Centers Unlocks High Efficiency of Visible‐Light Photo‐Fenton Water Cleaning Catalyst

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Bimetallic Cu and Fe oxide species supported on porous silica with interparticle mesoporosity act as efficient photo‐Fenton‐like catalysts under visible light. Photogenerated electrons drive the Cu2+/Cu1+ redox cycle. Part of Cu1+ is responsible for the regeneration of the Fe3+/Fe2+ cycle at neutral pH. Light irradiation additionally induces structural

Revealing Structure–Performance Relations in Core‐Shell Catalyst‐Based PEM Water Electrolyzer Anodes with Low Iridium Loading

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Table of Contents The TiO2@IrO2 core–shell architecture ensures high electronic conductivity even at a low iridium content of 10 wt%. The resulting catalyst layer shows significantly higher iridium utilization than a commercial reference, leading to improved PEMWE single‐cell performance at low iridium loading.

Impact of Electronic Substitution and Planarization on the Photophysical Properties of 2‐(2′‐Hydroxyphenyl)benzoxazole or 2‐(2′‐Hydroxyphenyl)‐Dimethylindole

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
We report the synthesis, structural characterization, and photophysical investigation of a series of Excited‐State Intramolecular Proton Transfer‐active HBO and HDMI derivatives. By varying heterocyclic cores, substituents, and ethynyl planarization, we establish structure–property relationships governing fluorescence behavior.

Synthesis and Properties of Cross‐Shaped Donor–Acceptor Dyes: Tunable Emission From Visible to Near‐Infrared in Solution and Solid‐State

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A comprehensive investigation (synthesis, electrochemistry, photophysics, and theory) of seven new cross‐shaped dyes based on N,N,N’,N’‐tetraphenyl‐1,4‐phenylenediamine cores substituted with different electron‐withdrawing groups, reveals tunable emission properties spanning the visible to near‐infrared range, both in solution and in the solid state ...
