Recent progress in research on stimuliresponsive circularly polarized luminescence based on π-conjugated molecules

Abstract

This short review article summarizes recent progress in research on various stimuli- responsive circularly polarized luminescence (CPL) properties derived from π-conjugated molecules and related materials. As representative examples, assembled structures of chiral π-conjugated polymers and molecules showed tunable CPL resulting from the enhancement of chirality induction by aggregation. Fascinating CPL-active species, pyrrole-based anionresponsive π-conjugated molecules exhibiting CPL induced by anion binding and ion pairing, are also discussed. © 2013 IUPAC.
