Synthesis of the first crystalline thiaanthracenes, 9-cyano- and 9-(ethoxycarbonyl)-10-methyl-10-thiaanthracenes and their reactions with electrophiles
thermodynamic affinities of the hydrogen adducts of the polar olefins (XH•) obtaining electrons in acetonitrile were determined using titration calorimetry and electrochemical methods. The pure C═C π-bond heterolytic and homolytic dissociation energies of the polar olefins (X) in acetonitrile and the pure C═C π-bond homolytic dissociation energies of the radical anions of the polar olefins (X•–) in acetonitrile

Described are visible light absorbing compounds. The compounds have a visible light absorption maximum between 430 and 480 nm and a full width half maximum (FWHM) at the visible light absorption maximum of at least 35 nm and up to 100 nanometers, wherein the compounds are photostable. The compounds substantially mimic the visible light absorbance properties of macular pigment while remaining photostable. The compounds may be used in a variety of articles, including ophthalmic devices.
