Structural Studies of the Self-aseemblies Created with Dipyrrins

Abstract

Three-dimensional superstructures of unique self-assemblies generated by exploring the conformational flexibility of various dipyrromethenes through creation of hydrogen-bonds with metal-halide anions are reported and the conformational diversity is thoroughly described in the solid and solution states by X-ray diffraction analysis and variable temperature NMR spectroscopy The tetrahedral or octahedral structures of their precursors. various metal-dipyrromethene complexes, are also reported, based on the crystallographic data STM images of the self-assemblies observed on graphite surfaces present interesting arrangements and appear as tubular bunches
