Reaction field for efficient porphyrin metallation catalysis produced by self-assembly of a short DNA oligonucleotide

Abstract

The G-wire structure, which is formed by dGTGGGTTGGGTGGGTTGG in the presence of 50 mM K⁺, becomes a catalytic reaction field for porphyrin metallation, inserting Zn²⁺ into porphyrin efficiently.
