  将高电子亲和力和分子内电荷转移结合在1,3-二硫代-硝基芴推挽二单元中。

  摘要：

  将富含电子的1,3-二硫醇-2-亚甲基连接到聚硝基芴电子受体上会导致形成高度共轭的化合物6至11，这些化合物将高电子亲和力与明显的分子内电荷转移（ICT）结合在一起，表现为强烈的可见光谱中的吸收带。光学和电子特性的这种罕见组合对于光电学中的几种应用是有益的。因此，将芴-二硫醇衍生物6a结合到光电导膜中提供了光热可塑性存储介质，其在ICT区域中具有显着增加的光敏性。分子的二硫醇和芴部分的结构变化很大，显示出ICT能量和还原电势与取代基的Hammett参数之间的极佳相关性。尽管仅观察到ICT波段很小的溶剂变色现象，但加热溶液会导致明显的蓝移，这可能是由于连接芴和二硫键部分的C9 = C14键周围扭曲增加的结果。7a，8a，10a，11a和13a的X射线晶体学分析证实了分子基态中的ICT相互作用。供体和受体之间的C9 ＝ C14双键基本上被延长，并且其长度随着二硫醇部分的供体特性的增强而增加。图

  New donor-pi-acceptor chromophores 5a-c, 7a-c, 8a-c, 13a-c and 14b-c have been synthesised: substituted 1,3-dithiole derivatives span a range of donor abilities [viz. 4,5-dimethyl > 4,5-bis(methylsulfanyl) > 4,5-bis(methoxycarbonyl)], a conjugated ethylenic or oligoethylenic linker varies the central pi-electron unit tone, two and four conjugated double bonds) and dicyanomethylene and N-cyanoimine groups are the acceptor units. Extended tetrathiafulvalene derivatives 15a-c have also been synthesised. The electronic absorption spectra of compounds 5, 7, 8 and 14 reveal a broad low-energy intramolecular charge-transfer band [lambda(max)(MeCN) 354-533 nm] which shifts bathochromically with increasing donor strength of the dithiole ring, and with increasing length of the conjugative pathway. The solution redox properties of 5, 7, 8 and 14, studied by cyclic voltammetry, reveal a reversible one-electron oxidation wave, attributed to the formation of the radical cation of the 1,3-dithiol-2-ylidene moiety, and an irreversible one-electron reduction to form the radical anion located on the dicyanomethylene or N-cyanoimine groups. For the bis(dithiole) donors 15a-c a single two-electron redox wave is observed. The non-linear optical (NLO) properties of 7a-c and 14b have been determined using the EFISH technique: moderate NLO properties are observed for compounds 7a-c [mu.beta(0) 85-112 x 10(-48) esu] whereas for the more extensively conjugated compound 14b, the value is increased to mu.beta(0) 1170 x 10(-48) esu. The molecular structure and electronic properties of the unsubstituted (R = H) compounds 7, 8, 1 8 and 15 have been calculated within the density functional theory approach. The minimum energy conformation corresponds to the trans orientation of the side chain for 7, and the cis orientation for 8, in agreement with X-ray crystal structures and solution NMR data. The redox properties and electronic spectra are discussed on the basis of molecular orbital energies and topologies. The X-ray crystal structures of compounds 7b, 8b and 15b are reported. In 7b the 1,3-dithiol-2-ylidene and dicyanopropene systems are planar and form an angle of 3 degrees between each other; the 'butadiene' unit has a trans configuration. Molecule 8b is planar (with the exception of the methyl groups) and the imine nitrogen atom is in a syn orientation towards the dithiole group, forming a short intramolecular S ... N contact [2.719(6) Angstrom]. For both 7b and 8b pi-delocalisation is observed within the central conjugated spacer unit. Molecule 15b has a predominantly planar structure, with the central tetraene unit in an all-trans configuration.

  Attaching electron-rich 1,3-dithiol-2-ylidene moieties to polynitrofluorene electron acceptors leads to the formation of highly conjugated compounds 6 to 11, which combine high electron affinity with a pronounced intramolecular charge transfer (ICT) that is manifested as an intense absorption band in their visible spectra. Such a rare combination of optical and electronic properties is beneficial for
