  Second-order nonlinear optical properties of tetrathiafulvalene-π-3-(dicyanomethylidene)indan-1-one chromophores

  摘要：

  Novel conjugated donor-acceptor chromophores, based on the strong electron donating tetrathiafulvalene moiety and the strong electron-withdrawing 3-(dicyanomethylidene)indan-1-one acceptor, exhibit large second-order optical nonlinearities. The effect of increasing the length of the polyenic spacer on the NLO properties of the new molecules has been studied by using the electric field-induced second harmonic generation (EFISH) method.

  四硫富瓦烯-多氯三苯甲基二元化合物：桥和开壳特性对线性和非线性光学性质的影响

  摘要：

  通过将四硫富瓦烯（TTF）电子给体单元通过不同长度的亚乙烯基单元桥接到聚氯三苯甲基（PTM）电子受体基团上，制备了三个共轭的供体-π-受体基团（1a - 1c）。分子内电荷转移对共轭桥的长度的依赖性已经通过不同的电化学和光谱技术进行了分析。通过将系统1 a – 1 c与非自由基类似物（2 a – 2 c）进行比较，可以计算出这些导数的线性光学性质和二阶非线性光学（NLO）响应。有趣的是，对于二元组1a，预计NLO反应增强– 1 c以自由基形式的PTM用于具有较长亚乙烯基桥的化合物。计算证实了桥在供体TTF和受体PTM单元之间进行电子通信方面所起的积极作用。

  (η6-arene)chromium complex as the acceptor moiety through a systematically increased conjugated bridge of vinylene units (12a−c, 16a−c) have been synthesized by Wittig−Horner olefination reaction. The electronic spectra as well as the electrochemical data reveal a different behavior of TTF derivatives (12a−c) and of exTTF derivatives (16a−c). Cyclic voltammetry shows the influence of the tricarbonylchromium

• Evidence for Two Separate One-Electron Transfer Events in Excited Fulleropyrrolidine Dyads Containing Tetrathiafulvalene (TTF)

  1,3-Dipolar cycloadditions of TTF-azomethine ylides (TTF = tetrathiafulvalene) to C-60 have been used to synthesize a series of novel donor-bridge-acceptor dyads. In these dyads the pyrrolidine[3',4':1,2][60]fullerene is covalently attached to the electron donor TTF either directly (5) or alternatively through one (2a) or two (7) vinyl groups. In the ground state, dyads 2a, 5, and 7 undergo Four quasireversible one-electron reductions and two reversible oxidation steps. The former are associated with the reduction of the C-60 core, whereas the latter correspond to the formation of the radical cation and dication of the TTF moiety, respectively. Semiempirical PM3 calculations reveal donor-acceptor distances of 4.8 Angstrom (5), 7.6 Angstrom (2a), and 10.5 Angstrom (7), and a deviation from planarity between the TTF fragment and the vinylogous spacer. In relation to an N-methylfulleropyrrolidine, the emission of the fullerene singlet excited state in dyads 2a, 5, and 7 is substantially reduced. Furthermore, the fluorescence quantum yield correlates well with the solvent dielectric constant and also with the spatial separation of the donor and acceptor moieties in the dyads. These correlation suggest that intramolecular electron-transfer processes evolving from the fullerene singlet excited state generate the (C-60(.-))-(TTF.+) pair. Pico- and nanosecond-resolved transient spectroscopy further substantiate a rapid transformation of the initially formed singlet excited state into the charge-separated radical pair with intramolecular rates ranging between 1.17 x 10(10) s(-1) and 1.47 x 10(9) s(-1). In all cases, the product of back electron transfer is the triplet excited state, which is generated with markedly high quantum yields (0.61-0.97). The latter is, in addition to the rapid primary intramolecular electron transfer, subject to a slower, secondary intermolecular electron transfer with rate constants of 7 x 10(8) M-1 s(-1) (5) in benzonitrile and 1.6 x 10(9) M-1 s(-1) (5) in toluene.
