Butterfly‐Shaped Guest Molecules Enable Tunable Room‐Temperature Phosphorescence in Host‐Guest Doped Systems

open access: yesAdvanced Science, Volume 13, Issue 2, 9 January 2026.
Butterfly‐shaped triphenylamine‐based guest molecules (DBDBD) doped into rigid host matrices (TPP, CA) achieve efficient, multicolor‐tunable room‐temperature phosphorescence (RTP). The host‐guest synergy enables ultralong afterglow (up to 4 s) and quantum yields (Φp = 3.42%), with applications in dynamic anti‐counterfeiting and information encryption ...

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

Marginal Stability of the YB1 Cold‐Shock Domain in Cells Enables Binding of Multiple Nucleic Acids

open access: yesAdvanced Science, Volume 13, Issue 1, 5 January 2026.
This study suggests that the marginal stability of the YB1 Cold‐Shock Domain (CSDex) allows for a balance between multifunctionality and conformational changes under physiological conditions. This balance is driven by the dynamic equilibrium between the unfolded ensemble (UE) and the native ensemble (NE) of CSDex (PDB:6LMR).

Electronic and Steric Tuning of Molecular Acidity toward Unified Models for Excited State Proton Transfer

open access: yesAdvanced Science, Volume 13, Issue 4, 19 January 2026.
Conventional excited‐state proton transfer (ESPT) theories explain the kinetics of fluorescent photoacids, but face challenges for weakly or nonfluorescent ones. This missing link is bridged by making and dissecting series of green fluorescent protein chromophore derivatives with varied photoacidities via strategic substitutions. Structure‐photoacidity

Determining Exciton Diffusion Length in Organic Semiconductors: Unifying Macro‐ and Microscopic Perspectives

open access: yesAdvanced Energy Materials, Volume 16, Issue 3, 21 January 2026.
Exciton diffusion length in organic semiconductor films is determined from encounter/annihilation rates. Non‐normalized exciton densities and proper intrinsic lifetime reference avoid over‐parametrization of the fits. Monte Carlo Simulation of individual molecule‐to‐molecule hops reproduce these results (②) when matching lattice constant and hoping ...
