One-touch Nanofabrication of Regular-sized Disks through Interfacial Dewetting and Weak Molecular Interaction

Nanodisks with uniform height and tunable diameter on the nanometer scale were constructed without any lithographic processes. The disks consisting of an amphiphilic triimide module were formed at the air–water interface in the presence of cyclen as an aqueous shackle and transferred onto substrates by the surface-touching (Langmuir–Schaefer) technique. The 3 nm height of the disks was maintained, whereas the diameter was tunable from 45 to 74 nm by varying surface pressures.
