Abstract

Recently, our research group reported a spectroscopic analysis of the light-switch effect in [Ru(bpy)₂(dppz)]²⁺ and one of its derivatives based on the “gap law”, revealing a change in the excited-state reorganization energy between the complex in aqueous solution and its DNA-intercalated form [1]. The present work shows that the structure of the intercalative ligand plays an important hole. The main structural feature of the dodppp ligand is a cyclic diamide moiety that forms a continuous extension of the dppz framework.
