  Synthesis of Ultrahighly Electron-Deficient Pyrrolo[3,4-d]pyridazine-5,7-dione by Inverse Electron Demand Diels–Alder Reaction and Its Application as Electrochromic Materials

  摘要：

  A new electron acceptor 6-alkylpyrrolo[3,4-d]pyridazine-5,7-dione (PPD) with a very low LUMO level has been synthesized via a challenging inverse electron demand DielsAlder reaction between thiophene and furan-decorated tetrazine substrates and an electron-deficient 1-alkyl-1H-pyrrole-2,5-dione unit. The PPD monomer has been incorporated into a series of donoracceptor-type conjugated polymers as electrochromic materials with good optical contrast, fast switching speed, and high coloration efficiency.

  日期：1975.12

  AbstractThe synthesis of unsymmetrical 3‐aryl and 3‐heterocyclic s‐tetrazines has been examined and the scope of the reaction and the product distribution is discussed. The products included unsymmetrical and symmetrical s‐tetrazines, hydrazines, diimides, tetrazoles and triazoles with the composition of the mixtures with respect to structural type varying with the individual reactions. Some transformations with the system are discussed.
