Mesogenic dipyrrins-building blocks for the fabrication of fluorescent and metal-containing materials

摘要

A new class of mesogenic dipyrrins is reported and their use in the fabrication of fluorescent and metal-containing self assembling materials is demonstrated.rnSince the early 1990's there has been a consistent and growing interest in the chemistry of 4,6-dipyrrins (2-(2H-pyrrol-2-ylidenemethyl)pyrroles) as bi-dentate ligands for the formation of metal complexes. Most commonly used for this purpose are the 5-aryl-4,6-dipyrrins derived by oxidation of the readily available 5-aryl-dipyrromethanes. Manipulation of the aryl group and/or metal ion has yielded many interesting complexes with differing metal : ligand ratios and geometries.
