  Novel Synthesis of Protected Thiol End-Capped Stilbenes and Oligo(phenylenevinylene)s (OPVs)

  摘要：

  The first general procedures for preparation of thiol end-capped stilbenes and oligo(phenylene-vinylene)s (OPVs) with tert-butyl- and acetyl-protected thiol termini have been developed. These reactions proceed via Br/Li exchange, McMurry, and Wittig-type reactions. The thiol functionality is protected against strong basic and acidic reaction conditions as a t-Bu sulfide. As a key point in the method, reprotection of the thiol group is accomplished by means of acetyl chloride and boron tribromide. The novel strategy forms the basis for stepwise introduction of 4-mercaptostyryl units in OPVs. The new mono-, di-, and trimercapto OPVs have potential applications as one, two, and three terminal molecular devices in gold nanoparticle clusters, self-assembled monolayers, and optoelectronic devices.

  New planar and soluble tris-tetrathiafulvalene derivatives with threefold-symmetry

  摘要：

  Novel trimeric tetrathiafulvalene (TTF) derivatives with threefold-symmetry are built on the 1,3,5-benzene core. Long alkyl chains have been incorporated on the peripheral positions of the TTF moieties in order to increase the solubility of the final products. Electrochemical and spectroscopic studies of the target compounds suggest that there are no significant interactions between the TTF units because of their meta orientation. Semiempirical theoretical calculations indicate that the new systems exhibit a high structural anisotropy resembling that exhibited by discotic liquid crystals. (C) 2000 Elsevier Science Ltd.

  A self‐assembly approach to tuning the optical properties of a star copolymer is reported herein. The star copolymer HCP‐star‐PEG with a hyperbranched conjugated polymer (HCP) core and many linear poly(ethylene glycol) (PEG) arms has been prepared successfully. The HCP core was synthesized by Wittig coupling of N‐(n‐hexyl)‐3,6‐diformylcarbazole and 1,3,5‐bis[(triphenylphosphonio)methyl]benzene tribromide

  本文报道了一种自组装方法，用于调节星形共聚物的光学性能。已成功制备了具有超支化共轭聚合物（HCP）核和许多线性聚乙二醇（PEG）臂的星形共聚物HCP- star -PEG。HCP核心是通过N-（n-己基）-3,6-二甲酰基咔唑和1,3,5-双[（三苯基膦酰基）甲基]苯三溴化物的Wittig偶联合成的。随后，通过酰基hydr连接将线性PEG臂接枝到HCP核心上。发现在氯仿溶液中，HCP- star- PEG的光学性质会因添加酸而发生变化。两者11 H NMR和UV / Vis光谱研究证实，光学性质的变化与酰基hydr基团中的酸和亚胺键的络合有关。HCP - star -PEG在氯仿和乙腈的混合溶剂中自组装成核壳胶束，这会影响亚胺键的质子化。因此HCP-的光学性质星-PEG可以通过自组装能够容易地控制。

  A novel star-shaped monomer 1,3,5-Tri[2-(3,4-ethylenedioxythien-2-yl)vin-1-yl]benzene (TEDOT-V-B) was synthesized by Wittig coupling reaction. The copolymers with BEDOT-V at different feed ratios were prepared onto the ITO-coated glass by cyclic voltammetry (CV) method and the electrochromic properties were reported. The influences of different feed ratios on the spectroelectrochemical and kinetic

  通过Wittig偶联反应合成了新型星形单体1,3,5-三[2-（3,4-亚乙二氧基噻吩-2-基）乙烯基-1-基]苯（TEDOT-VB）。通过循环伏安法（CV）将具有不同进料比的BEDOT-V的共聚物制备到涂有ITO的玻璃上，并报道了电致变色性能。研究了不同进料比对光谱电化学和动力学性质的影响。光谱电化学研究表明，共聚物膜的最大吸收波长红移地随着进料比而变化。另外，该共聚物具有可调的和低带隙。当BEDOT-VB / BEDOT-V的进料比为1：3时，共聚物薄膜的氧化切换时间最快，为0.9s（567 nm）和0.9s（967 nm），最快的还原切换时间为0.8s（ 567 nm）和0。9s（967 nm）。与PBEDOT-V相比，该共聚物通过进料比显示出可调色和多色电致变色现象，并实现了RGB颜色。另外，通过扫描电子显微镜（SEM）研究共聚物膜的表面形态。
