Intramolecular Charge‐Transfer Dopants Enable Isolated Triplet Excitons as Spin Qutrits in a Single Crystal

Angewandte Chemie, Volume 138, Issue 17, 20 April 2026.
Photoexcitation of an intramolecular charge‐transfer molecule doped into single crystals of a structurally similar host molecule results in well‐ordered, spectrally addressable, and orientation‐tunable triplet excitons that maintain coherence at elevated temperatures.

Improving Moist‐Electric Generator Stability and Performance by Enhancing Interfacial Activity With Crosslinked Aminated Carbon Dots

Carbon Neutralization, Volume 5, Issue 3, May 2026.
A high‐performance moisture‐enabled electricity generation (MEG) device with amino‐functionalized carbon dots on flexible fabric via thermal crosslinking is presented. The thermal crosslinking strategy enhances adhesion, removes inert groups, and suppresses carbon dots migration, boosting voltage (0.90 V vs. 0.56 V) and stability over 120 h.

Triple Matrix Confinement‐Induced Ultrabright Afterglow From Carbon Dots With Multivariate Responsive Afterglow Colors for Advanced Dynamic Information Encryption

Angewandte Chemie, Volume 138, Issue 16, 13 April 2026.
A novel carbon dots material (BUL‐CDs) with an initial afterglow brightness (406 cd m−2) far exceeding that of other afterglow luminescent materials was developed. Furthermore, the BUL‐CDs exhibited time‐dependent afterglow colors, excitation‐dependent afterglow colors, and thermochromic afterglow in response to triplet variables.

Mechanistic Insights Into the Photosensitizing Properties of the Topical Retinoid Tazarotene

ChemMedChem, Volume 21, Issue 8, 28 April 2026.
Light‐activated retinoids: Tazarotene and its active metabolite tazarotenic acid form long‐lived triplet excited states upon UVA irradiation, generating singlet oxygen and promoting photochemical reactions. These processes correlate with reduced fibroblast viability under light exposure, revealing potential phototoxicity and implications for combined ...
