Mode‐Selective C═C and C─N Vibrational Coupling Modulates Nonradiative Decay in Regioisomeric Organic Phosphorescent Emission

ABSTRACT Structural isomerization has emerged as an effective strategy for improving the performance of organic room‐temperature phosphorescent materials, but reported explanations are mainly attributed to differences in molecular packing, spin‐orbit coupling, excited‐state elect...

Water‐Mediated Reversible Crystalline Phase Transformation Enables Color Switching and Circularly Polarized Luminescence Handedness Inversion

ABSTRACT Stimuli‐responsive circularly polarized luminescence (CPL) modulation is highly sought for adaptive chiroptical systems, yet achieving reversible CPL handedness inversion in crystalline solids remains challenging. Here, we report organic ionic crystals composed of lumine...
