Planar, Fluorescent Push–Pull System That Comprises Benzofuran and Iminocoumarin Moieties Previously unknown, vertically linked heterocycles comprised of benzofuran and iminocoumarin moieties have been synthesized directly from 1,5-dibenzoyl­oxyanthra­quinone and aryl­aceto­nitriles via double Knoevenagel condensation followed by formal HCN elimination. The structural assembly of fully conjugated, electron-rich benzofuran and electron-deficient iminocoumarin is responsible for the strongly polarized nature of these heterocycles which translates into their polarity-sensitive fluorescence. dibenzoyl;HCN elimination;nature;Knoevenagel condensation;benzofuran;Fluorescent;assembly;heterocycle;Comprises Benzofuran;Planar;fluorescence;iminocoumarin moieties;aryl;Iminocoumarin MoietiesPreviously 2015-09-04
