Planar chiral [2.2]paracyclophane was employed as chiral scaffolds to twist an anthracene ring by tethering at its 1- and 8-positions; thus, twist chirality was induced in the anthracene moiety. The chiroptical properties of the resulting mol. I, including CD (CD) and circularly polarized luminescence (CPL), were found to be derived from the twist chirality. An analogous mol. II bearing long alkyl chains was a viscous liquid at ambient temperature, and its liquid film exhibited good CD and CPL profiles. Theor. studies were carried out to determine the origin of these properties in the ground and excited states, which reproduced well the exptl. results.
