Abstract
Optically active phenylene–ethynylene dimers with pyridine groups based on a planar chiral 4,7,12,15-tetrasubstituted [2.2]paracyclophane were synthesized. The chiral conformation was controlled by pyridine–Ag(I) coordinations. After Ag(I) coordination, the resulting higher-ordered structure dramatically enhanced the signal intensity of circular dichroism (CD) and decreased that of circularly polarized luminescence (CPL).
