| 1 | Visually constructing the chemical structure of a single molecule by scanning Raman picoscopy显示文摘The strong spatial confinement of a nanocavity plasmonic field has made it possible to visualize the inner structure of a single molecule and even to distinguish its vibrational modes in real space.W ith such ever-improved spatial resolution,it is anticipated that full vibrational imaging of a molecule could be achieved to reveal molecular structural details.Here we demonstrate full Raman images of individual vibrational modes at the angstrom level for a single Mg-porphine molecule;revealing distinct characteristics of each vibrational mode in real space.Furthermore,by exploiting the underlying interference effect and Raman fingerprint database,we propose a new methodology for structural determination,which we have called'scanning Raman picoscopy',to show how such ultrahigh-resolution spectromicroscopic vibrational images can be used to visually assemble the chemical structure of a single molecule through a simple Lego-like building process. | Yao Zhang Ben Yang Atif Ghafoor Yang Zhang Yu-Fan Zhang Rui-Pu Wang Jin-Long Yang Yi Luo Zhen-Chao Dong J.G.Hou | 2019 | National Science Review2019，6，6： | 5 |
