Notes:
Fluorescent dyes with a high sensitivity of their optical spectra towards changes of theenvironment were prepared via aldol condensation or Horner olefinations. The main chromophoreis a quadrupolar N-substituted 1,4-distyrylbenzene which allows protonation and complexation atvarious positions resulting in a series of different and significant changes of the optical spectra. Thesensitivity of the absorption and emission spectra on solvent polarity, acid, and cations is reported
