  "abstract": "Chiral organic emitters require a detailed understanding of structure-(chiro)optical property relationships. Herein, we design and synthesise a series of axially chiral BINOL-based enantiomers functionalized with aromatic ether substituents of increasing steric size and electronic extent, aiming to investigate how aromatic size and rigidity influence ground-and excited-state chiroptical responses. We started with a simple phenyl unit, followed by an extended naphthyl group. In contrast to sizedependent enhancement, the phenyl-and naphthyl-substituted derivatives exhibit similar absorption dissymmetry factors (gabs) across the 320-360 nm region, which indicates that linear p-extension alone does not significantly alter the chiroptical response. Therefore, we designed a more rigid structure using bi-naphthyl, with two covalently interconnected naphthyl units, which further restricted intramolecular rotation. As a result, an increase in gabs was observed. This result signifies the crucial role of conformational rigidity and suppression of intramolecular rotation in governing chiroptical amplification.",
