Abstract
Disclosed are optically active high-molecular-weight compounds of the following formula and stationary-phase materials containing the same. The high-molecular-weight compounds exhibit optical activity by virtue of their stacking helical structure wherein the aromatic groups are aligned in a twisted arrangement, thus being useful as optically active stationary phases for HPLC or polarized- light absorbers.
