Unlocking Spin Dynamics: Spin‐Orbit Coupling Driven Spin State Interconversion in Carbazole‐Containing TADF Emitters

open access: yesAdvanced Optical Materials, Volume 14, Issue 2, 14 January 2026.
This study explores overlapping charge transport mechanisms in TADF materials and identifies spin‐orbit coupling as the dominant mechanism for triplet‐to‐singlet transition in carbazole‐based cyanoarene emitters. Computational investigations reveal a second spin‐orbit‐coupling‐mediated reverse intersystem crossing pathway, significantly enhancing the ...

Review of Organic Persistent Phosphors: Classifications by Material Forms, Applications, and Mechanisms

open access: yesAdvanced Optical Materials, Volume 14, Issue 4, 27 January 2026.
Persistent luminescence (PersL), or afterglow, is the phenomenon of light emission that continues long after the excitation source is removed. This review systematically covers the historical development and major material forms of organic PersL materials, detailing their operating principles, mechanisms, and typical applications.

Comparison of the Performance of Fluorescent, Phosphorescent, and TADF Luminophores for Explosives Sensing

open access: yesAdvanced Sensor Research, Volume 5, Issue 1, January 2026.
Both singlet and triplet populations of the TADF compound 4CzIPN are quenched upon interaction with dinitrotoluene by photoinduced electron transfer. However, their quenching rate is different, with the triplet excitons being more efficiently quenched due to a combination of their longer lifetime and larger population.

Sulfur‐Embedded Pure Green Multiple Resonance TADF Emitters: Optimizing Photophysical and Electroluminescent Properties

open access: yesAdvanced Science, Volume 13, Issue 3, 14 January 2026.
Sulfur atoms are inserted into the multiple‐resonance thermally activated delayed fluorescence framework for developing pure green emitters. The analogous isomers present distinguishing photophysical and electroluminescent properties. The better emitter‐based non‐sensitized device exhibits a maximum external quantum efficiency of 36.4% and a remarkable

RNAi Regulator C3PO Promotes Arbovirus Infection in Insect Vectors

open access: yesAdvanced Science, Volume 13, Issue 4, 19 January 2026.
RNA interference (RNAi) is vital for eukaryotes to defend against virus infection. The C3PO complex takes part in RNAi but its role in regulating viral infection remains unclear. This work finds that insect C3PO facilitates arbovirus replication by degrading precursors of miRNAs, especially miR‐971‐3p.
