In this manuscript, stereospecific synthesis of C2- and C1-sym. pyrene fused [7]helicene compounds I and II, resp. was portrayed. Compounds I and II were synthesized via one-pot Suzuki coupling-C-H activation and two-step Suzuki coupling-Scholl reaction, resp., with complete retention of configuration. The synthesized mols. differ in the fusing mode of [7]helicene units with pyrene via six- and seven-membered rings for compounds I and II, resp. There was a significant difference in the functional properties and enantiomerization barrier of both compounds because of their distinct mol. symmetry as well as fusing mode to pyrene moiety. The heptagon containing mol. II showed remarkable photophys. and chiroptical properties with commendable configurational stability compared to compound I and pristine [7]helicene as well as its [5]helicene congener.
