Overview

Randomized trial demonstrates unprecedented skeletal rearrangement in porphyrin precursors, highlighting unique chemical properties.

Key Points

  • The aim is to explore a novel skeletal rearrangement in porphyrin macrocycles upon deposition on a hot surface.
  • Deposition onto a hot Ag(111) surface
  • Analysis of structural changes in porphyrin precursors
  • The porphyrin precursor expands from an 18-π to a 20-π structure
  • Insertion of carbon atoms from -CF3 groups into the macrocycle is observed
