  Fast Photochromic Polymers Carrying [2.2]Paracyclophane-Bridged Imidazole Dimer

  摘要：

  The synthesis and photochromic behavior of the fast photochromic polymers carrying [2.2]paracyclophane-bridged imidazole dimer are demonstrated. A significant feature of this synthetic strategy is that we can modify the photochromic properties such as coloration/decoloration rate, coloring, and photosensitivity via the stepwise synthetic approach of the imidazole dimer system. Notably, the photochromic behavior of the polymers is not affected by the environment around the photochromes and copolymerization with other monomers in both solution and film, which cannot be realized in any other conventional photochromic systems. The comparable photochromic behavior of the homopolymers and copolymers in solution and film indicates that the photochromic unit is independent from the local environment, which allows effective molecular design of the photochromic monomer unit to accomplish desired photochromic properties of the polymer.

  region. Electrochemical and optical properties of [Ni(dpedt)2] depend strongly on the nickel bis(1,2-dithiolene) core and very slightly on the alkyl chain lengths or configurations. These highly soluble coordination compounds are potential candidates as acceptor solution-processable materials for active layers in organic electronic devices, such as field effect transistors or photovoltaic devices.

  日期：2000.2

  A three-component coupling of tetramethylammonium pentacarbonyl(acyl)chromates, aryl iodides, and CO takes place under CO atmosphere in the presence of a catalytic amount of Pd(PPh3)4 to afford the corresponding unsymmetrical α-diketones in good yield. By performing the reaction under argon atmosphere, unsymmetrical ketones are prepared instead of α-diketones.

  在 CO 气氛中，在一定量的 Pd(PPh3)4 催化下，四甲基五羰基（酰基）铬酸铵、芳基碘化物和 CO 发生三组份偶联反应，以良好的收率得到相应的非对称 α-二酮。在氩气环境下进行反应，可以制备出不对称酮，而不是 α-二酮。
