Abstract

This study elucidates a novel phenomenon in chiral AIEgens crystalline materials, demonstrating solvent-induced circularly polarized luminescence (CPL) sign inversion while maintaining identical helical configuration and molecular chirality in the crystalline state. The observed CPL reversal originates from non-bonding interactions between co-crystallized solvent molecules and AIEgens, which modulate the θ_μ,m (S₁→S₀) of electric and magnetic transition dipole moments within the unit cell. The findings establish a unique mechanism for chiroptical property manipulation through supramolecular engineering of non-covalent interactions in crystalline systems (e70003).

本研究阐明了手性AIEgens晶体材料中的一种新现象，证明了溶剂诱导的圆极化发光（CPL）符号反转，同时在晶体状态下保持相同的螺旋构型和分子手性。所观察到的CPL反转源于共结晶溶剂分子与AIEgens之间的非键相互作用，这种相互作用调节了胞内电跃迁和磁跃迁偶极矩的θμ，m （S1→s）。这些发现建立了一种独特的机制，通过晶体系统中非共价相互作用的超分子工程来操纵热学性质（e70003）。
