Item type:Publication, Access status: with files , Single molecule thermal gearing effect(Elsevier, 2026-01-16); ; ; ; Observation of a thermally activated gearing effect between two hexa- tert -butyl-decacyclene (HBDC) molecule-gears is reported using the Au(111) surface to constrain lateral diffusion of the molecules at 77 K. An on-purpose selected small 2D HBDC nano-island is first destabilized using the tip of a scanning tunneling microscope (STM) in a soft-pulling mode of molecular manipulation. It follows a long sequence of thermally activated spontaneous molecular reconfigurations, leading up to a molecular gearing effect. Using coupled Langevin equations, a simulation of this thermal process is proposed to determine the conditions for this thermally activated gearing effect.Publicationtype: Journal Article24 16
