    名称:
    Imine-Bridged Planar Poly(phenylenethiophene)s and Polythiophenes
    摘要:
    Synthetic routes to soluble planar poly(phenylenethiophene)s and polythiophenes are described. The main polymer backbones are synthesized via Pd(0)-catalyzed couplings of the electron-rich N,N'-(bis-tert-butoxycarbonyl)-3,4-diamino-2,5-bis(tri-n-butylstannyl)thiophene with electron-deficient aryldibromodiones. The prebridged polymers have bathochromically shifted absorptions due to donor/acceptor interactions between the consecutive repeat units. Upon exposure of the polymers to trifluoroacetic acid or titanium tetrachloride, imine bridges are formed that force the consecutive units into planarity. The bridging units are sp(2)-hybridized, thus allowing for greater electron delocalization between the consecutive aryl units. The syntheses of model trimeric systems were conducted to provide further data for assessing the optical properties of the polymers. Protonation of the imine moieties causes bathochromic shifts of >100 nm in several cases. The effect is explained by an intramolecular charge transfer. Thus these arrangements of planar structures with imine bridges serve as optically based proton sensors with spectral shift differences far-exceeding those of nonplanar imine-containing polymers.

    分散驱动手性扭曲 PAH 双螺旋的形成
    摘要:
    合成了一系列具有多达 25 个线性环状苯环的单分散多环芳烃 (PAH),并通过单晶 X 射线衍射对其进行了很好的表征。通过分散和弱π堆积驱动的分子间相互作用,在构象灵活的单体链之间产生独特的双螺旋结构。这一贡献可以激发新型人工双螺旋的设计。
