Handedness Tunable Circularly Polarized Luminescence of Hydrogen-Bonded Supramolecular system

摘要

Chiral organic compounds emitting circularly polarized luminescence (CPL) have recently attracted considerable attention as smart photonic materials. A versatile molecular design to efficiently afford high performance CPL, especially handedness (sign) control, is highly required.1 Imai et al. have reported an unprecedented CPL sign tunability of axially chiral biaryl compounds depending on their dihedral angles.2
