Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>A comprehensive study on the physicochemical properties of a series of mono‐ and diaza[5]helicenes as well as mono‐ and diaza[6]helicenes is reported. Through the use of both computational and experimental methods, these helically chiral pyridohelicenes with the nitrogen atom(s) in various positions are characterised according to their inversion barriers, protonation constants and redox potentials. By using DFT calculations, kinetic measurements, UV/Vis titrations, cyclic voltammetry and EPR spectroscopy, a self‐contained picture of their behaviour under conventional treatment by heat, acids and oxidising/reducing agents is provided.</p> </abstract>
