Solvent Effect on Self-Assembled Structures of 3,8-Bis-hexadecyloxy-benzo[c]cinnoline on Highly Oriented Pyrolytic Graphite

3,8-Bis-hexadecyloxy-benzo[c]cinnoline (BBC16) self-assembled into two structures at highly oriented pyrolytic graphite (HOPG) surface:  one was formed by molecules with a V-like configuration (C 2 v symmetry) and the other by molecules with a Z-like configuration (C s symmetry). The self-assembled...

Summary:3,8-Bis-hexadecyloxy-benzo[c]cinnoline (BBC16) self-assembled into two structures at highly oriented pyrolytic graphite (HOPG) surface:  one was formed by molecules with a V-like configuration (C 2 v symmetry) and the other by molecules with a Z-like configuration (C s symmetry). The self-assembled structures could be tweaked by the solvents used. In the self-assembled monolayers (SAMs) on HOPG, the BBC16 molecule adopted the V-like configuration in polar solvents and the Z-like configuration in nonpolar solvents. Moreover, the solvent viscosity, solvent dissolvability of BBC16, and substrate temperature also played some roles in tuning the two-dimensional self-assembled structures.
