Facile Synthesis of π-Extended Viologens: Electron-Deficient Polycyclic Aza-aromatics

Abstract

A novel family of π-extended viologens has been synthesized by a concise 3-step route from simple and readily available chemicals. The π-enlargement gives the system new photophysical and electrochemical properties such as photoluminescence and changed redox potentials.

Keywords: chromophores; density-functional calculations; photoluminescent; viologens; π-extended.
