Abstract

meta-Ethynylpyridine 18-mer associates with octyl β-D-glucopyranoside to show an induced circular dichroism (CD) band at around 337 nm in CH2Cl2. The addition of copper(II) triflate and o-phenanthroline enhanced the CD band. Even when an equimolar amount of β-L-glucopyranoside was added to make the system racemic, the CD was memorized and remained for several weeks.
