Assemblies of Fluorine Containing Bent-Shaped Liquid Crystal Molecules Studied by Using Scanning Tunneling Microscopy
In this work we prepared a fluorine containing bent-shaped liquid crystal from biphenyl as the central core and rod-like azobenzene mesogens as the side arms, namely 4′,3-biphenyl bis[4-(4′-hexadecanloxy-3-fluorophenylazo)benzoate] (L104). The self-assembly behaviors of L104 molecules on graphite surface were investigated by using scanning tunneling microscopy (STM) under ambient conditions. The high-resolution STM images of L104 assemblies revealed three kinds of structures showing the joint effects of dipole–dipole interactions originated from the fluorine and the bent-core alignments for maximizing – interactions. These observations may be beneficial for understanding the assembly mechanism and designs for novel banana-shaped liquid crystal molecules.
