to clamp the molecular conformation and facilitate parallel packing of achiral D-A molecules. This leads to spontaneous symmetry breaking during crystallization. When this emergent homochirality is coupled with the optical gain of the molecules, the homochiral crystals can be explored as excellent circularly polarized micro-lasers with low lasing threshold (16.4 μJ cm−2) and high dissymmetry factor
我们报告了一种合理的策略来钳制分子构象并促进非手性
DA 分子的平行堆积。这导致结晶过程中自发的对称性破缺。当这种出现的单手性与分子的光学增益耦合时,单手性晶体可以作为具有低激光阈值 (16.4 μ J cm -2 ) 和高不对称 因子g lum ( 0.9 )的优秀圆偏振微型激光器进行探索。
