Circularly polarized luminescence: an easy path from molecules to supramolecular systems and beyond

This tutorial offers an easy access point to the hot topic of circularly polarized luminescence (CPL), focusing on organic materials. Some basic concepts about chiroptical responses are presented and the subtleties associated with reliable CPL measurements are summarized. A brief overview of models for CPL is illustrated, with main focus on supramolecular systems, before addressing the challenging topic of circularly polarized electroluminescence.
