Kinetic controlled hierarchical self-assemblies of all-trans-retinoic acid on Au(111) — •Chao Li and yongfeng Wang — Key laboratory for the physics and cemistry of nanodevices, Department of Electronics, Peking University, Beijing 100871, China

Kinetic controlled hierarchical self-assemblies of all-trans-retinoic acid on Au(111) are investigated by low-temperature scanning tunneling microscopy (STM) in ultra-high vacuum. The dominant molecular hierarchical superstructure can be selectively controlled to dimer, tetramer, or pentamer patterns, which are stabilized by hydrogen bonds and vdW interactions.
