Cationic π‐conjugated polymers form an interchain helically π‐stacked assembly with anionic chiral compounds that is stabilized by both electrostatic and π−π interactions to hierarchically self‐organize into a spherulite with a circularly polarized blue luminescence. To the best of our knowledge, this is the first example of a chiroptical spherulite that is hierarchically constructed from π‐conjugated polymers.
