Jiang Group reports new imaging record!
The Jiang group in our department have applied their imaging and spectroscopy methods to distinguish two structurally very close structural skeletons (regioisomers) with 8 Angstrom spatial resolution. In selective heterogeneous catalysis reaction, two or more regioisomers are commonly obtained as products. For the first time, a topological and chemical analysis of two regioisomers mixed structures with single-molecule sensitivity was achieved using tip-enhance Raman spectroscopy (TERS). Their study holds broad and diverse applications, and can make significant advancement in lots of areas in surface chemistry and nanotechnology including selective heterogeneous catalysis reactions, single-molecule imaging, modern-day electronic devices and so forth. This result is published in the journal Nano Letters. For more information, see https://pubs.acs.org/doi/10.1021/acs.nanolett.9b00826
