Der ideale Polymethinzustand

Abstract

The theory of the ideal polymethine state equally existing between the aromatic state and the polyene state (triad theory) provides a comprehensive understanding of the chemistry and physics of conjugated organic compounds. This is shown by modelling new colorants, by investigating of the light-induced charge transfer (CT) and charge resonance (CR), by examination colour and constitution relationships, by the interpretation of reactivity, by elucidating the origin and limitations of linear free energy relationships, and by designing organic metals and organic materials with nonlinear optical properties.The present state of the art challenges writers of textbooks in organic chemistry to adapt the theory of the ideal polymethine state as an intrinsic part of the chemistry of conjugated organic compounds.
