Dynamic axial chirality control of a carboxybiphenol through acid-base interaction
A novel, fluorescent 2.2'-biphenol bearing two carboxyl and two ethynyl groups was found to be sensitive to the chirality of the chiral diamines, thus showing an induced circular dichroism due to an excess single-handed, axially twisted conformation.
