  combination of 13C NMR spectroscopic and electrochemistry measurements. Donor-substituted CEEs display strong intramolecular charge-transfer (CT) character, resulting in intense, bathochromically shifted CT bands in the UV/Vis spectrum. Their structural diversity establishes them as suitable models for the study of pi-conjugation and band gap tuning in strong charge-transfer chromophores. The extent of pi-conjugation

  合成了一系列广泛的甲硅烷基保护的氰基乙炔（CEE）和N，N-二甲基苯胺基供体取代的CEE。通过选择性的甲硅烷基脱保护和随后的氧化炔键偶联，可以构建更多的发色团。通过13 C NMR光谱学和电化学测量的结合揭示了CEE的强电子接受性质。供体取代的CEE表现出很强的分子内电荷转移（CT）特性，导致在UV / Vis光谱中出现强烈的红移的CT带。它们的结构多样性使它们成为研究强电荷转移生色团的π共轭和能带隙调谐的合适模型。通过结合基态技术研究了供体取代的CEE中pi共轭的程度，例如X射线晶体学，电化学，B3 LYP计算和NMR光谱学。将这些基态结果与在UV / Vis光谱中观察到的特征进行比较后发现，与预期相反，更广泛的pi共轭可导致具有强供体和受体部分的分子带隙更大。

A trans-bis(triisopropylsilyl)-protected derivative represented an exception and could be isolated as stable crystals. X-Ray analysis revealed that the two bulky (i-Pr)3Si groups isolate the reactive chromophores from one another in the crystal and prevent

  The synthesis. characterization, and photophysical as well as electrochemical properties of the photochromic hybrid systems 11-16 and 18, which contain photoswitchable tetraethynylethene (TEE: 3,4-diethynylhex-3-ene-1,5-diyne) and dihydroazulene (DHA) moieties, are presented. The molecular photoswitches were synthesized by a Sonogashira cross-coupling reaction between an appropriate TEE precursor (6-10 and 17) and an iodinated DHA 1 or its vinylheptafulvene (VHF) isomer (4) (Schemes 5-7). X-Ray crystal structures of five DHA derivatives (1. trans-11a, cis-11a, 12, and 13) are discussed (Figs. 2-5). In all compounds, the cyclohexatriene moiety of the DHA chromophore adopts a clear boat conformation (Table I). presumably due to crystal-packing effects. the arylated TEE moieties in the hybrid systems show substantial distortions from planarity, with the dihedral angles between the plants of the central TEE core and thr adjacent aryl substituents amounting to 43. The switching properties were investigated by electronic absorption spectroscopy. Upon light absorption. DHAs 1. 12-16. and 18 underwent retro-electrocyclization in solution to give the corresponding VHFs( Figs h. II. and 12). The reaction is thermally reversible, with half-lives tau (1,2) between 3.9 and 5.8 h at 2.5 in CH2Cl2 (Figs. 7 and 13 and Table 3). A comparatively slower (E) - (Z) isomerization process about the central C=C bond of the TEE moiety was also observed. The N,N-dimethylanilino-(DMA) substituted TEE-DHA hybrid systems trans-11a and cis-11a did not react to the corresponding VHFs upon irradiation (Scheme 9). Instead. only the reversible (E) - (Z) photoisomerization of the TEE core occurred (Fig. 10 and Table S). This process was further investigated for photofatigue bq electronic-emission spectroscopy (Fig. 17). After protonation of the DMA group, the usual DHA - VHF photoreaction took place. Compound 11 represents a three-way chromophoric molecular switch with three addressable sub-units (TEE core, DHA/VHF moiety, and proton sensitive DMA group) that can undergo individual. reversible switching cycles (Scheme 9). A process modeling the function of an 'AND' logic gate (Fig. 19) and three writc/erase processes could be performed with this system. Cyclic and linear sweep-voltammetry studies in CH2Cl2 (+ Bu4NPF6) revealed the occurrence of characteristic first-reduction steps in the TEE-DHA hybrid systems between - 1.6 and - 1.8 V L'S. Fc/Fc. (ferrocene/ferricinium couple) (Table 5). Oxidations occur at cn. +1.10 V. After photoisomerization to the VHF derivatives. reduction steps at more positive and oxidation steps at mt,re negative potentials H ere recorded. No DHA - VHF isomerization took place upon electrochemical oxidation or reduction (Fig. 20).
