The right mix: By mixing a Lewis basic polymer with a Lewis acid, the optical properties of the polymer can be tuned. The formation of an adduct results in red-shifted absorbance and photoluminescence spectra, increase in the emission yield, and a longer excited-state lifetime. This strategy was successfully implemented to modulate the electroluminescence of a polymer light-emitting diode.
