How Aromatic Are Molecular Nanorings? The Case of a Six‐Porphyrin Nanoring** [PDF]

open access: yesAngewandte Chemie - International Edition, 2021
Abstract Large conjugated rings with persistent currents are novel promising structures in molecular‐scale electronics. A six‐porphyrin nanoring structure that allegedly sustained an aromatic ring current involving 78π electrons was recently synthesized.

Free-Standing Bimetallic Nanorings and Nanoring Arrays Made by On-Wire Lithography

ACS Nano, 2010
This paper describes a new strategy for synthesizing free-standing bimetallic nanorings and nanoring arrays based upon on-wire lithography and a galvanic replacement reaction. The strategy allows one to tune the diameter, length, and therefore aspect ratio of the nanorings.

Ultrafast Vibrations of Gold Nanorings

Nano Letters, 2011
We investigate the vibrational modes of gold nanorings on a silica substrate with an ultrafast optical technique. By comparison with numerical simulations, we identify several resonances in the gigahertz range associated with axially symmetric deformations of the nanoring and substrate.
