    operationally simple homocoupling reaction that targets the convenient synthesis of organic-electronically important building blocks. A variety of synthetically useful bithiophene derivatives and functionalized biphenyls are efficiently prepared by an on-water and under-air protocol using Pd/C as catalyst. We find that Pd/C gives generally higher and cleaner homocoupling conversions than using Pd(OAc)2 in the
    我们在此报告了一种操作简单的均偶联反应,其目标是方便合成有机电子重要的结构单元。各种合成上有用的联噻吩衍生物和官能化联苯可通过水上和空气中协议使用Pd / C作为催化剂有效地制备。我们发现,在(杂)芳基碘化物的情况下,由于Pd(OAc)2的存在,与使用Pd(OAc)2相比,Pd / C的同质耦合转化率更高且更清洁。引发更多的副反应,包括脱卤和低聚。在最佳条件下,对酯,酮,醛,腈,硝基,氯和溴等官能团的耐受性良好。我们希望本方法学将为绿色化学与基于噻吩的有机材料的桥接做出宝贵的合成贡献。

Theoretical calculations performed on three different heptaphyrins, 4, 5, and 17, also reveal that the inverted structures are approximately 35-40 kJ lower in energy relative to the corresponding noninverted structures.

    An easy and efficient synthetic methodology for two hitherto unknown tropylium-cation-fused Hückel aromatic [26] dicarbaporphyrinoids has been developed by acid-catalyzed Lindsey type condensation of bithiophene/biselenophene diol with azulene using BF3 · Et2O followed by oxidation with chloranil and/or DDQ. Both the macrocycles have been achieved in moderately good yields. Their structures, aromaticity and optical properties have been elucidated by NMR, UV-vis-NIR spectroscopic analyses and in-depth theoretical calculations. Both the macrocycles exhibited strongly diatropic characteristics with the UV-vis spectra closely resembling the spectra for true porphyrins. Detailed structural analyses using 1H–1H COSY, ROESY and DFT level theoretical investigations indicated fully conjugated [26][Formula: see text] main conjugation pathway being benefitted by the tropylium character of the seven membered rings.

    尽管在基于聚硒烯的分子系统上已经取得了很大进展,但是由于聚合过程中单体的不稳定性以及缺乏合适的单体前体,母体聚硒烯的不良光电性能仍然妨碍了此类材料的基本理解和实际应用。在这项工作中,我们开发了一种有效的方法,通过逐步增加电化学聚合反应的初始单体链长来提高母体聚硒烯的光电性能和稳定性。我们发现,单体结构从硒烯到二硒烯和三硒烯的链长增量显着降低了电聚合潜力,因此能够形成具有更好的共轭结构和更少的结构缺陷的高质量聚硒烯薄膜。由三硒苯形成的聚硒苯具有较低的光学带隙(1.72 eV),更好的氧化还原活性和稳定性,并显着改善了红色和蓝色之间可逆和稳定的颜色变化的电致变色性质,具有高性能,包括高达75%的出色光学对比度,高达450厘米的高着色效率2  C -1,非常快的切换时间(氧化时间为0.7 s,还原时间为0.4 s)。所制备的聚硒二苯醚薄膜的这些有利性能提供了图案化的柔性电致变色器件的成功制造,其
