Several bis‐cinnoline derivatives were found to act as a new class of n‐type amorphous organicmaterial. They exhibit highelectron‐drift mobility up to the order of 10−3 cm2V−1 s−1 and highthermalstability, and therefore are useful as a cathode buffer layer in thin‐layer organic solar cells.

(aq) (X = Br or Cl) and NaNO2, followed by spontaneous ring closure to give a mixture of 4-halocinnoline and 4-cinnolinone products. The different products result from competing attack of X− and H2O, respectively, upon an intermediate 2-alkynylphenyl diazoniumion during the cyclization step. In order to improve the chemoselectivity of this reaction, we have utilized triazenes as masked diazonium ions

Starting from triazene bound ortho-halo arenes on a solid support, palladium-catalyzed alkynylations and subsequent cleavage reactions under acidic conditions give rise to ortho-alkynylaryldiazonium salts, which in turn undergo cyclization to afford substituted 4-halo- and 4-hydroxycinnolines in moderate to good yields. The method is applicable to automated synthesis. (C) 1999 Elsevier Science Ltd. All rights reserved.
