摘要：

(Figure Presented) Triplex-rated: Discrete self-assembly of Fe III ions with octahedral coordination geometry occurs within triple-stranded artificial DNA with hydroxypyridone nucleobases as metal ligands through the formation of nonplanar base triplets. Such a novel structural motif in DNA could lead to programmable alignment of six-coordinate transition metals. © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
