Strong circularly polarized luminescence induced from chiral supramolecular assembly of helical nanorods†
Abstract
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 glum values can be up to 0.079.
