Circularly Polarized Blue Luminescent Spherulites Consisting of Hierarchically Assembled Ionic Conjugated Polymers with a Helically π-Stacked Structure

Cationic pi-conjugated polymers form an interchain helically pi-stacked assembly with anionic chiral compounds that is stabilized by both electrostatic and pi-pi 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 pi-conjugated polymers.
