  • Photoresponsive Crown Ethers. 19. Photocontrol of Reversible Association-Dissociation Phenomena in “Tail(Ammonium)-Biting” Crown Ethers
    作者:Seiji Shinkai、Tohru Yoshida、Kiminori Miyazaki、Osamu Manabe
    DOI:10.1246/bcsj.60.1819
    日期:1987.5
    The aggregation properties of photoresponsive crown ethers (1) having a crown ring and an ammonioalkyl (H3N+–(CH2)n−, n=4, 6, 10) group attached to the two sides of an azobenzene have been evaluated through the measurements of average molecular weights and electric conductance. Osmometric determination of average molecular weights established that all trans-isomers (trans-1 (n=4, 6, 10)) form the pseudocyclic dimers due to intermolecular crown-ammonium complexation. Photoisomerized cis-1 (n=6) and cis-1 (n=10), which have been designed so that intramolecular “biting” of the ammonio group to the crown can occur upon photoisomerization, existed as the discrete monomers. On the other hand, cis-1 (n=4), which cannot form the intramolecular “tail-biting” complex because of the short tetramethylene spacer, existed as the pseudo-cyclic dimer. This difference was well reflected by electric conductance: in 1 (n=6) and 1 (n=10), the conductance increased synchronously with trans-to-cis photoisomerization and decreased with cis-to-trans photoisomerization. Such a photoresponsive conductance change was scarcely detected for 1 (n=4). Furthermore, the additives which enforce dissociation of the dimeric species to the monomeric species suppressed the magnitude of the photoinduced conductance change. This is a novel example that the light energy is transmitted to the conductance change.
    通过测量平均分子量和电导率,评估了具有冠环和连接在偶氮苯两侧的烷基(H3N+-(CH2)n-,n=4、6、10)的光致发光冠醚(1)的聚集特性。平均分子量的渗透测定结果表明,所有反式异构体(反式-1(n=4、6、10))都因分子间冠络合而形成了伪环二聚体。光异构化的顺式-1(n=6)和顺式-1(n=10)在光异构化时,基与冠发生分子内 "咬合",从而以离散单体的形式存在。另一方面,顺式-1(n=4)由于含有短的四亚甲基间隔,不能形成分子内 "咬尾 "复合物,而是以假环二聚体的形式存在。电导率很好地反映了这种差异:在 1(n=6)和 1(n=10)中,电导率随反式到顺式的光异构化同步增加,随顺式到反式的光异构化同步减少。而在 1(n=4)中几乎检测不到这种光致电导变化。此外,强制二聚物解离为单体的添加剂抑制了光诱导电导变化的幅度。这是光能传递到电导变化的一个新例子。
  • Crown-ether and azobenzene-containing liquid crystalline polymers: An influence of macromolecular architecture on optical properties and photo-orientation processes

    DOI:10.1002/pola.24472
    日期:2011.2.1
    ether‐containing photochromic comb‐shaped liquid crystalline polyacrylates with different macromolecular structure of side groups were synthesized and investigated. Phase behavior, optical and photo‐optical properties of thin spin‐coated films of these polymers were studied. A special attention was paid to a comparative study of the photo‐orientation phenomena occurring in the polymer films under a polarized light
