discotic nickel bis(1,2-diphenyl-1,2-ethenedithiolene) complexes [Ni(dpedt)2], including thirteen new compounds, have been synthesized by new short and efficient synthetic pathways. Physical investigations show that these complexes are thermally stable, possess good electron-accepting properties, and absorb light strongly in the near-infrared spectral region. Electrochemical and optical properties of
15 种中性长链取代的盘状镍双(1,2-二苯基-1,2-乙烯二硫烯)配合物 [Ni(dpedt)2],包括 13 种新化合物,已通过新的短而有效的合成途径合成。物理研究表明,这些配合物是热稳定的,具有良好的电子接受性能,并在近红外光谱区强烈吸收光。[Ni(dpedt)2] 的电化学和光学性质适度取决于连接到配合物苯环上的官能团。它们的 LUMO 和 HOMO 能级分别在 –4.7 至 –5.0 和 –5.7 至 –6.0 eV 的范围内。两个八(n-烷氧基)-取代的配合物表现出具有六方对称性的柱状液晶相。
