Molecular recognition of nucleosides and nucleotides based on circular dichroism induced by helix formation of poly[(4-dihydroxyborophenyl)acetylene]

Poly[(4-dihydroxyborophenyl)acetylene] was found to form a predominantly one-handed helical conformation upon complexation with various nucleosides and (oligo)nucleotides, and the complexes exhibited characteristic, split-type induced circular dichroisms depending on the nucleobases.
