Helical-ribbon and tape formation of lipid packaged [ru(Bpy)3 ]2+ complexes in organic media

Abstract

Anionic lipid amphiphiles with [RuII (bpy)3 ]2+ complex have been prepared. The metal complexes have been found to form ribbon and tape structures depending on chemical structures of lipid amphiphiles. Especially, the composites showed hypochromic effect and induced circular dichroism in organic media, and flexibly and weakly supramolecular control of morphological and optical properties have been demonstrated.
