    摘要:
    Thirteen novel dipolar and V-shaped chromophores with pyranylidene electron-donating part, diazine electron-withdrawing part and various pi-linkers were synthesized. The extent of intramolecular charge transfer, structure-property relationships and optical properties were further investigated by UV/Vis absorption, electrochemistry, and DFT calculations.

    Linear and V-Shaped Nonlinear Optical Chromophores with Multiple 4H-Pyran-4-ylidene Moieties
    摘要:
    A simple synthesis of dipolar one- and two-dimensional chromophores bearing two or three 4H-pyran-4-ylidene moieties is reported. Whereas the pyranylidene fragments acting as donors are proaromatic, the spacer one is not. In the linear derivatives, Chain elongation gives rise to a sharp increase in the second order nonlinear optical responses, but some V-shaped derivatives display first hyperpolarizabilities (beta) lower than those of their linear analogues. This uncommon feature lends experimental support to previous theoretical studies on the relative contribution and sign of the beta-tensor components.

  • Aromatic/Proaromatic Donors in 2-Dicyanomethylenethiazole Merocyanines: From Neutral to Strongly Zwitterionic Nonlinear Optical Chromophores

    whereas 4H‐pyran‐4‐ylidene‐ and 4‐pyridylidene‐containing compounds are zwitterionic and 1,3‐dithiol‐2‐ylidene derivatives are close to the cyanine limit, anilino‐derived merocyanines are essentially neutral. This very large range of intramolecular charge transfer (ICT) gives rise to efficient second‐order NLO chromophores with μβ values ranging from strongly negative to strongly positive. In particular
    制备了推挽式化合物,其中一个芳香族电子供体与一个2-二氰基亚甲基噻唑受体结合。与具有芳香族供体的模型化合物相比,它们的性能更佳。结合实验(X射线衍射,1 H NMR,IR,拉曼,UV / Vis,非线性光学(NLO)测量)和理论研究表明,结构和溶剂效应决定了这些花菁的基态极化:而4 H含吡喃-4-亚烷基和4-吡啶亚基的化合物为两性离子型,1,3-二硫醇-2-亚烷基衍生物接近花青的限度,苯胺衍生的花菁本质上是中性的。分子内电荷转移(ICT)的范围非常广,可产生高效的二阶NLO生色团μβ值的范围从强负到强正。尤其是,吡喃亚烷基衍生物不寻常,因为它们在加长π间隔物时显示出ICT程度的提高,而该特征在于它们显示出的非常大的负μβ值。将形式为喹啉的2-二氰基亚甲基噻唑部分与原芳香族供体连接起来似乎是优化两性离子NLO发色团的一种有前途的方法。

    first time the reactivity of this system towards aldehydes. Their ground state polarization and linear and second-order nonlinear optical (NLO) properties have been determined by a combined experimental and theoretical study, and compared to those of analogous compounds featuring an aromatic thienothiophene unit. Due to the gaining of aromaticity, quinoid systems have been found to display more polarized

  • Polarization, second-order nonlinear optical properties and electrochromism in 4H-pyranylidene chromophores with a quinoid/aromatic thiophene ring bridge

    between compounds that only differ in the character (quinoid or aromatic) of the thiophene unit shows a more efficient ICT for the quinoid thiophene-containing chromophore, which influences the second-order NLO response. Furthermore, the thienyl ring has been also found to play a significant role in the ICT process for the analogous aromatic derivative.
    制备了推挽系统,其中原芳香族的4 H-吡喃亚基电子供体通过作为电子继电器的一部分的喹啉噻吩与二氰基亚甲基受体共轭,并且已将其性能与母体化合物的性能进行了比较。具有芳族噻吩部分。不同的实验技术(X射线衍射,1 H NMR,IR,拉曼,紫外可见,循环伏安法,光谱电化学和NLO测量)与理论计算相结合已用于发色团的研究。quinoidal衍生物虽然是中性的,但显示出强烈的极化结构,具有正的μβ值和分子内电荷转移(ICT)在加长π间隔物时逐渐增加。仅在噻吩单元的特征(喹啉或芳族)方面不同的化合物之间的比较显示,含醌噻吩的生色团的信息通信技术效率更高,这会影响二阶NLO反应。此外,还发现噻吩基环在ICT过程中对于类似的芳族衍生物起着重要的作用。
