Two types of optically active cyclic compounds based on planar chiral [2.2]paracyclophane skeleton are synthesized. These compounds comprise tetrasubstituted [2.2]paracyclophanes as chiral crossing units, in which π-conjugated phenylene-ethynylenes are folded to construct ribbon- and propeller-shaped structures. The compounds emit circularly polarized luminescence (CPL) with high anisotropy factors (|g _lum|) and CPL brightness values (B _CPL).
