Indolo‐Fused MR‐TADF Materials and their Application in Organelle‐Targeted Bioimaging
Advanced Functional Materials, Volume 36, Issue 63, 6 August 2026.Using indolo‐fusion and sulfur bridging, four multi‐resonance thermally activated delayed fluorescent (MR‐TADF) materials are reported based on the quinolino[3,2,1‐de]acridine‐5,9‐dione (QAO) framework. Functionalization of these dyes with phosphonium groups enables cellular imaging with mitochondrial targeting in glassy organic nanoparticles ...

Advanced Optical Materials, Volume 14, Issue 29, 7 August 2026.Magnetoluminescent (ML) diradicals exhibit field‐dependent emission due to magnetic field‐dependent spin state populations and spin‐dependent emission properties. In this work, quantum chemical calculations applied to the first reported ML diradical provide evidence of the different deactivation pathways of the excited singlet and triplet states and ...

Tuning Iminothioindoxyl Photoswitches Toward Photopharmacological Applications
ChemPhotoChem, Volume 10, Issue 8, August 2026.Shifting the iminothioindoxyl (ITI) photoswitch absorption spectrum toward the NIR window can be achieved through a combination of push and pull substituents and acidochromism. Photopharmacology offers precise control over the activity of biological systems using light, with photoswitches being increasingly used as reversible modulators of drug ...

Solvatochromism in Solvent Mixtures: A Practical Solution for a Complex Problem
LiquidsMany reactions are carried out in solvent mixtures, mainly because of practical reasons. For example, E2 eliminations are favored over SN2 substitutions in aqueous organic solvents because the bases are desolvated.

Accessing Sn≥2 States of a TADF Emitter by Femtosecond NIR Spectroscopy
Chemistry – A European Journal, Volume 32, Issue 26, 11 July 2026.The depicted thermally activated delayed fluorescence (TADF) emitter was studied by femtosecond near‐infrared (NIR) spectroscopy. A prominent NIR transition was shown to be strongly solvent‐dependent, with implication for intersystem crossing in the compound.
