New Triazaborine Chromophores: Their Synthesis via Oxazaborines and Electrochemical and DFT Study of Their Fundamental Properties
Original language description
Eight new and stable triazaborine chromophores featuring various substituents as donor and acceptor moieties were prepared and investigated. Interpretation of the measured electrochemical data (CV, RDV, and dc-polarography), and UV/Vis spectra as well asthe quantum chemical calculations was presented. In the homologous series the first reduction proceeds as a one-electron reversible process localized at the -N=C-C=N- part of the central heterocycle being in conjugation with the attached carbonyl. The first oxidation of triazaborines proceeds as a two-electron irreversible process, most probably of the ECE type, localized at the negatively charged boron atom and surrounding unsaturated structures including the substituted phenyl ring. For better understanding of the relationship between the structure and redox properties, the LFER approach was applied for the first oxidation as well as reduction potential using the Hammett' sigma (para) substituent constants.
