Chiral supramolecular assemblies (BNS-BPP) can be self-assembled by electrostatic and π-π stacking interactions between the chiral binaphthyl sulphonate (BNS) anion and the achiral bipyrene-based pyridinium (BPP) cation chromophore. BNS-BPP can exhibit strong CD and circularly polarized luminescence (CPL) signals, and the dissymmetry factor g values can be up to 0.079.
手性超分子组装体（BNS-BPP）可通过手性联萘磺酸酯（BNS）阴离子与非手性联芘基吡啶鎓（BPP）阳离子发色团之间的静电相互作用和π-π堆积相互作用进行自组装。BNS-BPP可表现出强烈的圆二色性（CD）和圆偏振发光（CPL）信号，且不对称因子g值可达0.079。
