Abstract

Chiral carboxylic acid/amine and sulfonic acid/amine supramolecular organic complexes composed of biphenyl units were successfully prepared using achiral biphenylcarboxylic acid (or biphenylsulfonic acid) derivatives and chiral 1-phenylethylamine as component molecules. The solid-state circular dichroism (CD) and fluorescent properties of the supramolecular complexes change significantly with the type and number of binding groups.
