meso-Free dipyrrins: Formation of assembled structures including a 2D ordered pattern

Abstract

Fairly planar meso-unsubstituted dipyrrins, some of which had trialkoxyphenyl moieties, were synthesized. They underwent self-assembly in less polar solvents and the derivative bearing aliphatic chains exhibited a 2D ordered pattern at the solid/liquid interface, as observed through scanning tunneling microscopy.
