Electrochemically-sensitized circularly polarized luminescence – E-Polar

Chirality is a fundamental property of symmetry at all scales, from (bio)molecules to (nano)particles and up to macroscopic objects. Besides its fundamental role played in living organisms where it enables biological functions, chirality is of paramount importance in light-matter interaction as well as in advanced technologies including spintronics, quantum technology, information processing, and opto-electronics. Nowadays, circularly-polarized light (CPL) is practically obtained from non-polarized light sources by using polarizers, yielding devices with reduced efficiency, more complex architecture and hard to miniaturize. Therefore, there is currently an urge of chiral emitters that intrinsically and efficiently emit CPL for highly-performing devices scalable down to the molecular scale. Finding methods to electrically (over optically) address CPL emitters featuring enhanced dissymmetry factors is a key-enabling step for their application in electrically-driven advanced devices and next-generation technologies. The multidisciplinary and challenging project E-Polar aims at exploring a novel concept of generating efficient circularly polarized luminescence in molecular materials. The successful achievement of these goals will pave the way for a paradigm-shift in the field and will enable downsized solid-state CPL light-emitting devices with applications beyond the proof-of-concept herein proposed.
