  OPE/OPV H-mers: synthesis, electronic properties, and spectroscopic responses to binding with transition metal ions

  摘要：

  A new type of structurally defined H-shaped OPE/OPV co-oligomers (termed H-mers) functionalized with various donor and/or acceptor end groups was synthesized by iterative Sonogashira coupling and Horner-Wadsworth-Emmons (HWE) reactions. Electronic substitution effects on the H-mer backbone were investigated by UV-vis absorption and fluorescence spectroscopy. Some H-mers were found to show spectral responses upon binding to an acid (TFA) or transition metal ions, revealing the applicability of H-mers in the field of chromophore and fluorophore based chemosensors.

  Cruciform-like molecules with two orthogonally placed π-conjugated systems have in recent years attracted significant interest for their potential use as molecular wires in molecular electronics. Here we present synthetic protocols for a large selection of cruciform molecules based on oligo(phenyleneethynylene) (OPE) and tetrathiafulvalene (TTF) scaffolds, end-capped with acetyl-protected thiolates

  近年来，具有两个正交放置的 π 共轭系统的类十字形分子因其作为分子电子学中的分子线的潜在用途而引起了极大的兴趣。在这里，我们提出了基于低聚（亚苯基乙炔基）（OPE）和四硫富瓦烯（TTF）支架的大量十字形分子的合成方案，末端用乙酰保护的硫醇盐作为电极锚定基团。对分子进行了对其导电性能以及溶液中光物理和电化学性能的综合研究。分子的复杂性质及其在连接处不同配置中可能的结合需要不同的电导测量技术：(1) 自组装单层 (SAM) 的导电探针原子力显微镜 (CP-AFM) 测量，(2) 机械控制断裂结 (MCBJ) 测量，以及 (3) 扫描隧道显微镜断裂结 (STM- BJ) 测量。CP-AFM 测量显示了来自 OPE3 和 OPE5 十字形分子系列的 SAM 的结构-性能关系；SAM 的电导随着沿线的二硫富烯 (DTF) 单元 (0, 1, 2) 的数量增加而增加，并且当用两个 DTF 单元取代 OPE3
