    摘要: A method for altering the electronic and optical properties of a chemical compound having a band gap and a framework that includes π-delocalized electrons. The method includes complexing a Lewis acid to a basic site within the framework to form a Lewis acid adduct having a band gap that differs from the band gap of the chemical compound. The λmax of the Lewis acid adduct can be shifted to a longer wavelength in comparison to the λmax of the chemical compound. In various versions, the chemical compound can be a conjugated oligomer, a conjugated polymer, or a small molecule comprising a conjugated π-electron system. Electronic devices that include Lewis acid adducts are also provided.
