  Electrochemical synthesis, characterization and electrochromic properties of indan and 1,3-benzodioxole-based poly(2,5-dithienylpyrrole) derivatives

  摘要：

  Indan and 1,3-benzodioxole groups were introduced to the central pyrrole ring of the dithienylpyrrole- based conducting polymers backbone, which are denominated as PIND and PMDOB, respectively. The two series of dithienylpyrrole-based polymers were electrochemically synthesized, and the cyclic voltammograms showed the redox properties of electrochemically prepared films deposited at various scan rates. Spectroelectrochemical investigations conducted in this study showed that PIND and PMDOB films are yellowish-green and yellow color, respectively, in the neutral state; they can be reversibly oxidized and reduced and this is accompanied by obvious color changes. Maximum optical contrast (Delta T-max) of the P(IND-co-perylene) s and P(MDOB-co-perylene) s films were measured as 60.7 % at 932 nm and 64.8 % at 962 nm, respectively, in an ionic liquid solution, and the maximum coloration efficiency (h) of P(IND-co-perylene) s and P(MDOB-co-perylene) s films were calculated to be 199.2 and 209.7 cm(2) C (1), respectively, in an ionic liquid solution. Electrochromic devices (ECD) based on PIND and PMDOB as anodic polymers and poly(3,4-(2,2-diethylpropylenedioxy) thiophene) (PProDOT-Et-2) as cathodic polymer were constructed. PIND/PProDOT-Et-2 ECD showed a high Delta T-max (33.1%) at 582 nm and satisfactory redox stability, whereas PMDOB/PProDOT-Et-2 ECD showed a high coloration efficiency (375.9 cm(2) C (1)) and satisfactory optical memories.

  摘要：

  本申请公开了一种制备5‑羟甲基糠醛的方法。该方法将六碳糖类化合物、离子液体和酸性催化剂直接进行混合得到混合物，反应过程中抽真空将水带走，得到5‑羟甲基糠醛。该方法在温和条件下以离子液体作为溶剂来制备HMF的方法，在此发明中由于反应温度较低，基本无副反应发生，反应后溶液澄清透明，这为分子筛用于催化此反应提供了可能。

• IONIC LIQUID MEDIATED SOL-GEL SORBENTS

  公开（公告）日：2012-05-24

  Ionic liquid (IL)-mediated sol-gel hybrid organic-inorganic materials present enormous potential for effective use in analytical microextraction. One obstacle to materializing this prospect arises from high viscosity of ILs significantly slowing down sol-gel reactions. A method was developed which provides phosphonium-based, pyridinium-based, and imidazolium-based IL-mediated advanced sol-gel organic-inorganic hybrid materials for capillary microextraction. Scanning electron microscopy results demonstrate that ILs can serve as porogenic agents in sol-gel reactions. IL-mediated sol-gel coatings prepared with silanol-terminated polymers provided up to 28 times higher extractions compared to analogous sol-gel coatings prepared without any IL in the sol solution. This study shows that IL-generated porous morphology alone is not enough to provide effective extraction media: careful choice of the organic polymer and the precursor with close sol-gel reactivity must be made to ensure effective chemical bonding of the organic polymer to the created sol-gel material to be able to provide the desired sorbent characteristics.
