Abstract

The complex [Ru(phen)2(dppz)]2+ (phen = 1,10-phenanthroline, dppz = dipyrido[3,2-a∶2′,3′-c]phenazine) was attached to the 5′ end of a short oligonucleotide to form conjugates, the Δ-isomer of which showed a high cooperativity during the recognition of the repetitive sequence, while the Λ-isomer did not.
