This research delves into the adsorption and rotation characteristics of N-Heterocyclic Carbene with Thiophene adsorbed on an Au (111) surface, employing Low Temperature Scanning Tunneling Microscopy in Ultra High Vacuum (LT-UHV STM) conditions. The molecule under investigation displays two distinct chiralities and maintains a flat/planar configuration. The molecule demonstrates rotation (chirality independent) around sulfer upon voltage pulses with the STM tip.
