Structure and ionicity of intramolecular charge transfer zwitterions, D delta+-pi-A(delta-)
Intramolecular charge transfer (CT) compounds (Ddelta+-pi-A(delta-)) were synthesized by the reaction between enamine and TCNQ. The CT transition energy (hv(CT)) showed the solvent dependence (solvatochromism). The ionicity of these compounds was deduced from the plot of hv(CT) against the solvent polarity. The plot exhibited abnormal behavior.
