Straightforward self-assembly of porphyrin nanowires in water: Harnessing adamantane/β-cyclodextrin interactions

Abstract

A convenient approach for the self-assembly of welldefined porphyrin nanowires in water, wherein the individual monomers do not aggregate via π-π interactions, is disclosed. These unidirectional and heteromeric assemblies are instead composed of robust β-CD/adamantane host/guest interactions. A combination of surface microscopies and fluorescence energy transfer experiments were conducted on the nanowires demonstrating their stability and resistance to disassembly. © 2010 American Chemical Society.
