Abstract

Abstract : The effect of molecular symmetry on CPL properties was first demonstrated in triple heterohelicenes by the newly synthesized triple oxa[6]helicene. Abstract : We present the synthesis and characterization of the first triple oxa[6]helicene with C 3 symmetry. In contrast to the reported D 3 -symmetric triple oxa[7]helicene, the C 3 -symmetric analogue holds parallel electric and magnetic transition dipole moments and thus enhanced luminescence dissymmetry, shedding light on the critical role of molecular symmetry on chiroptical response.
