Enantiopure 1,1Ј:4Ј,1Π‰-ternaphthalene compounds were synthesized via enantioresolution of 1,1Ј:4Ј,1Π‰-ternaphthalene-2,2Π‰-dimethanol (2) by the chiral phthalic acid amide method. The CD spectra of chiral 1,1Ј:4Ј,1Π‰-ternaphthalene compounds synthesized showed typical intense exciton split CD Cotton ef
