Abstract
Near-infrared luminescent ytterbium(III), neodymium(III), and erbium(I II) complexes containing novel organic chromophores derived from azatr iphenylene have been prepared and spectroscopically studied. The compl exes can be excited from 350 to 450 nm, leading after intramolecular e nergy transfer to intense lanthanide luminescence in acetonitrile. Que nching of the luminescence of the complexes by molecular oxygen reveal s information on the rate of energy transfer from the ''antenna'' to t he lanthanide ion. (C) 1998 Elsevier Science Ltd.
