Chiral Pyrrole-Based Polyaromatics

In recent years, there has been significant interest in incorporating heteroatoms into polycyclic aromatic hydrocarbons (PAHs). This exploration of heteroatom-doped variants of extended π-conjugated materials has revealed their distinct and enhanced electronic and photophysical properties. Among the various five-membered aromatic heterocycles, pyrrole stands out as the most electron-rich when compared to its isoelectronic counterparts, furan and thiophene. The synthetic versatility and strong redox activity of pyrrole enable the creation of synthetic frameworks with enhanced p-doping and other desirable material properties.<br/>Our research has focused on the synthesis and characterization of novel chiral pyrrole-based PAHs. These include twisted azacoronenes and helicenes incorporating pyrrole units. We are currently investigating their chiroptical, electrochemical, and magnetooptical properties.
