Alternated stacks of nonpolar oligo(p-phenyleneethynylene)-BODIPY systems

Abstract

Supramolecular chemistry: The self-assembly of an oligo(p- phenyleneethynylene)-4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (OPE-BODIPY) system into alternated 1D π stacks in solution exhibited liquid-crystalline properties at room temperature. This system represents a new approach towards a controlled dye organization exclusively driven by π-π interactions (see figure). Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
