  π-扩展的四硫富瓦烯（TTFs）衍生的二阶非线性光学器件的推挽生色团的合成和性质

  摘要：

  通过π共轭低烯间隔基（14a – c – 16a – c）连接到对硝基苯基电子接受单元的新型π扩展四硫富瓦烯（exTTF）衍生物显示出良好的二阶光学非线性。寡烯间隔子的共轭长度和π共轭桥中噻吩环的存在（20a – c）已在理论上（PM3）和/或实验上（EFISH技术）进行了研究。已通过循环伏安法（CV）研究了新型化合物的氧化还原特性，并且CV数据显示了exTTF单元的良好供体能力。虽然这些化合物显示的分子内电荷转移（ICT）谱带的能量及其氧化还原电位对连接供体和受体部分的共轭间隔基的性质相当不敏感，但观察到其二阶非线性光学响应有所增加在增加共轭长度上。带有噻吩环的化合物20a – c具有出色的热稳定性，分解温度超过400°C。一系列新的D-π-A化合物（23a – c）还合成和研究了带有1，3-二硫醇-2-亚烷基供体单元的）。

  Synthesis and Properties of the First Highly Conjugated Tetrathiafulvalene Analogues Covalently Attached to [60]Fullerene

  摘要：

  The synthesis of the first C-60-based donor-acceptor (D-A) systems (12a-c) in which the C-60 core is covalently linked to strong, highly conjugated pi-electron donors derived of tetrathiafulvalene (TTF) with p-quinodimethane structure has been carried out by cyclization with azomethine ylides following Prate's procedure. The synthetic strategy requires the preparation of the novel formyl-substituted pi-extended donors which, in turn, are prepared in a multistep synthetic procedure by reaction of 2-formyl-9,10-anthraquinone (6) with the appropriately substituted phosphonate esters (8). Semiempirical PM3 calculations predict a geometry highly distorted from planarity for the donor fragment and a most stable conformation in which both 1,3-dithiole rings are far away from the [60]fullerene surface. The redox properties were determined by cyclic voltammetry in solution and reveal the presence of four cathodically shifted reduction waves, relative to C-60 and corresponding to the C-60 core, and a two-electron single oxidation wave to form stable dication species of the pi-extended donor units. Magnetic susceptibility measurements clearly indicate a paramagnetic behavior in the solid state, and a remarkable conductivity is observed for these single component organic compounds.

  The gain of aromaticity and planarity, associated with the oxidation of a π-extended TTF electron donor, is the key feature for obtaining strong stabilisation of photolytically generated radical pairs in novel C60-based dyads.

• Donor/Acceptor Fulleropyrrolidine Triads

  New C-60-based triads, constituted by a fulleropyrrolidine moiety and two different electroactive units [donor I-donor 2 (10, 15a,b), or donor 1-acceptor (17, 21)], have been synthesized by 1,3-dipolar cycloaddition reaction of azomethyne ylides to C-60 and further acylation reaction on the pyrrolidine nitrogen. The electrochemical study reveals some electronic interaction between the redox-active chromophores. Triads bearing tetrathiafulvalene (TTF) and ferrocene (Fe) (10) or pi-extended TTFs and Fe (15a,b) show reduction potentials for the C-60 moiety which are cathodically shifted in comparison to the parent C-60 In contrast, triads endowed with Fe and anthraquinone (AQ) (17) or Fe and tetracyanoanthraquinodimethane (TCAQ) (21) present reduction potentials for the C-60 moiety similar to C-60 Fluorescence experiments and time-resolved transient absorption spectroscopy reveal intramolecular electron transfer (ET) processes from the stronger electron donor (i.e., TTF or extended TTF) to the fullerene singlet excited state, rather than from the poorer ferrocene donor in 10, 15a,b. No evidence for a subsequent ET from ferrocene to TTF.+ or pi-extended TTF.+ was observed.

  A new series of electroactive triads (10a-c) has been prepared by Knoevenagel condensation of formyl-containing pi -extended TTFs (9a-c) to a suitably functionalized dimer (8) derived from the electron acceptor TCAQ. The electronic spectra of the triads (10a-c) show the presence of an intramolecular charge transfer (ICT) band from the donor pi -extended TTF unit to the conjugated carbonyl groups. Theoretical calculations at the semiempirical PM3 level predict different geometrical structures for the triads which rule out a through space electronic interaction between the donor (pi -extended TTF) and acceptor (TCAQs) moieties. Cyclic voltammetric measurements reveal the amphoteric behaviour of triads 10a-c and a negligible electronic interaction between the redox chromophores. (C) 2001 Elsevier Science Ltd.

  New push pull dyes featuring pi-extended tetrathiafulvalene (exTTF) as the donor group and tricyanofuran (TCF) as the acceptor group were synthesized and characterized. Their broad absorption covers the entire visible spectral range and enters the near-infrared region. Electrochemistry and theoretical calculations provided an understanding of these singular electronic properties. The new dyes are appealing candidates as light harvesters in photovoltaic devices.
