Substituent dependence of a fluorescence energy of the 8-quinolinolato anion (Q[sup -]) was systematically investigated with electronic structure calculations. Large red- and blueshifts of the fluorescence were predicted for Q[sup -] with the NO[sub 2] and CN groups, respectively. For bis(8-quinolinolato)berylium with the NO[sub 2] and CN groups, the emission energies were calculated to be 1.56 eV (795 nm) and 2.66 eV (466 nm), respectively, indicating that they are potential candidates as red- and blue-light-emitting compounds. © 2001 American Institute of Physics.

    Quinones are ubiquitous in nature and constitute an important class of naturally occurring compounds found in plants, fungi and bacteria. Human exposure to quinones therefore occurs via the diet, but also clinically or via airborne pollutants. For example, the quinones of polycyclic aromatic...
