Abstract

Two-dimensional porous networks self-assembled in solution are rare, while maintaining the solution-phase network structure upon casting on solid supports presents a major challenge. We report on oligoarylacetylene bearing amphiphilic perylene diimide moieties that self-assemble into a two-dimensional porous network in aqueous solution that can be cast on surfaces, while maintaining the porous structure. The networks were characterized by cryogenic electron microscopy (cryo-TEM and cryo-SEM), and by atomic force microscopy, revealing formation of thin porous films (4-nm thick). The network can be cast on various solid surfaces, preserving its solution-phase structure. The design motif utilizing an oligoarylacetylene backbone with interacting amphiphilic pendants appears to be of wide utility for formation of novel assembly patterns.
