From: A chiral molecular propeller designed for unidirectional rotations on a surface
Shape and structure of the molecular propeller. a Chemical structure of the molecule. b Top view of the ball and stick model of the molecule. color code: Dark red = Br, gray = H, black = C atoms on the Cp(PhBr)5, violet = B, yellow = S, green = other atoms on the indazole fragments (ethyl groups are omitted for clarity). c A large area STM image of molecular propellers on Au(111) at 80 K. Tripod structures are stationary. Blue arrows point to rotating propellers. Gray dashed lines highlight the herringbone structure of Au(111). STM images showing a stationary (d) and rotating molecular propeller (e). [STM imaging parameters for c, d, and e: Vt = −1 V, It = 70 pA]
