Phosphahelicenes: from chiroptical and photophysical properties to OLED applications

Abstract : Herein, we report experimental physico-chemical and chiroptical properties of a series of phosphahelicenes, focusing on their UV/Vis absorption, luminescence, electronic circular dichroism (ECD), optical rotations, and circularly polarized luminescence. Furthermore, detailed analysis of absorption and ECD spectra performed with the help of quantum-chemical calculations allowed us to highlight general features of these helicenic phosphines. Finally, due to well-suited electrochemical properties and thermal stability, the systems were successfully used as emitters in organic light-emitting diodes.
