A strategy has been developed for switching chemical reactions between two identical reagents on the basis of DNA duplex-triplex transition. In response to the change of solution pH, a DNA complex changes its conformation and repositions chemical reagents that are conjugated with DNA strands. As a result, chemical reactions are reprogrammed. This strategy is expected to be applicable to sophisticated chemical syntheses.
