In this paper, we describe the stereospecific synthesis and functional properties of C2– and C1-sym. pyrene-fused [5]helicene mols. 1 and 2 connected via hexagonal and heptagonal rings, resp. Both mols. showed high configurational stability and distinct functional properties, which were attributed to the fusing mode of [5]helicene with the pyrene and mol. symmetry. The estimated Gibbs activation energy for enantiomerization of 2 is one of the highest reported values for any π-conjugated mols. incorporating [5]helicene moiety.
