• Preparation of a Polymer with Limited<i>π</i>-Conjugation Length: A Polymer Containing Quaterthiophene Units
  作者：Masa-aki Sato、Masao Hiroi

  DOI：10.1246/cl.1996.495

  日期：1996.6

  A polymer containing quaterthiophene units in the main chain was prepared by electrochemical polymerization of 1,2-bis(3′-hexyl-2,2′-bithiophene-5-yl)ethane. The obtained green film had a conductivity of 2 × 10−2 S cm−1 in oxidized states and was neutralized by immersing in methanol. The cyclic voltammograms of the neutral film showed only an oxidation process in the first cycle.

  通过1,2-双(3'-己基-2,2'-二噻吩-5-基)乙烷的电化学聚合制备了主链中含有四联噻吩单元的聚合物。获得的生膜在氧化态下具有 2 × 10-2 S cm-1 的电导率，并通过浸入甲醇中和。中性膜的循环伏安图仅显示第一个循环中的氧化过程。

  [GRAPHICS]A series of the title dimeric quinquethiophenes linked with a di- to hexamethylene spacer was synthesized and examined as a pi-dimer model of polythiophene. Upon two-electron oxidation with iron(III) chloride in dichloromethane, they readily form intramolecular pi-dimer species, except for the dimethylene-linked dimer that cannot be bent into a pi-stacked structure.

  Two quaterthiophene-based dimers including an ethylene bridge have been designed and efficiently prepared; experimental and computational studies show a promising potential as semiconducting material with a charge transport of higher dimensionality compared to quaterthiophene.
