Formation of a charge transfer complex within a hydrophobic cavity in DNA†
Abstract
We now show that a hydrophobic cavity created within the DNA can work as a scaffold to form a charge transfer (CT) complex composed of naphthalenediimide (NDI) and dialkoxynaphthalene (DAN) derivatives. The formation of the CT complex resulted in stabilization of the duplex structure through stacking interaction, which was comparable to the natural base pairs.
