Significance

The introduction of quinoidal structures often makes a significant contribution to the optical and electronic properties of π-conjugated systems. Quinoidal character generally lowers the band gap of the system resulting in red-shifted and often near-infrared absorption. Many quinoidal compounds also exhibit amphoteric redox behavior. Solubility issues have complicated the synthesis of large π-conjugated polycyclic aromatic hydrocarbons.
