A series of oligonaphthodioxepins was synthesized, revealing a helically arranged octamer, ( R , R , R , R , R , R , R )‐ 3 , which showed intense circularly polarized luminescence (CPL) both in solution and in the solid state. The fluorescence quantum yields (Φ FL ) in solution and in the solid state were 0.90 and 0.22, respectively, and the g lum values in solution and in the solid state were +2.2×10 −3 and +7.0×10 −3 , respectively. This is one of the highest solid‐state CPL g lum values yet reported. The high Φ FL and g lum values were due to the rigidity, as well as to the fact that ( R , R , R , R , R , R , R )‐ 3 was a non‐planar molecule. Moreover, ( R , R , R , R , R , R , R )‐ 3 was highly stable both chemically and stereochemically.
