Abstract

In this study, chiral carbon nanorings D₃-(P)-NR5 and D₃-(M)-NR5 with outstanding chiral linear and nonlinear optical properties were synthesized. They exhibit excellent circularly polarized luminescence (CPL) with a high CPL brightness of 1008 M⁻¹ cm⁻¹ and a significant second-harmonic generation circular dichroism response with a high anisotropy factor of up to 0.59.
