Studies of 2-azaazulenium derivatives - 3: The nature of electron transitions and spectral properties of styryl dyes containing terminal groups of different types

10.1016/j.molstruc.2012.08.034

The study focuses on the quantum-chemical investigation and spectral measurements of 2-azaazulium (AA) derivatives, specifically examining the molecular geometry, electron structure, and spectral properties of styryl dyes containing terminal groups of different types, including dimethylaminostyryls, methoxystyryls, and methylstyryls. These dyes were compared with analogous dyes containing 2-benzimidazolim and 4-pyrylium residues. The chemicals used in the study served to explore the nature of electron transitions and the dependency of electronic transitions and π-electron density distribution on the electron asymmetry degree of dye molecules. The purpose was to understand the differences in spectral properties and charge distribution between these types of extremely unsymmetrical cyanines and to propose a new classification of terminal groups of cyanine dyes based on their electronic structure and transitions.
