  "abstract": "Fully deuterated [9]cycloparaphenylene ([9]CPP- d 36 ) was synthesized by gold-mediated macrocyclization. Although the molecular geometry and π-electronic structure of [9]CPP were retained, the framework vibrational frequencies were lowered. Solid-state [9]CPP- d 36 showed a higher fluorescence quantum yield than [9]CPP (0.46 vs 0.34), demonstrating H/D substitution as a vibrational-modulation approach for enhancing nanohoop fluorescence.",
