A small library of new benzanthrone α-aryl-α-aminophosphonates has been synthesized by solvent-free one-pot reaction of 3-aminobenzanthrone, different aromatic aldehydes and dialkylphosphonates under Kabachnik-Fields reaction conditions. FTIR, 1H-, 13C-, 31P-NMR spectroscopy, mass spectrometry and X-ray diffraction crystallographic analysis has confirmed structures of novel dyes. Photophysical properties of studied α-aminophosphonates have been investigated by means of UV-Vis and fluorescence spectroscopy in various organic solvents. Thermogravimetric analysis (DTA and TG) has been used to outline thermal stability of obtained derivatives. Morphology, electrolyte leakage, MDA and pigment quantification experiments were carried out to determine toxic effect on growth of wheat sprouts.
