2-Aminothiophene derivatives are the key intermediates for the present synthesis. It is known that the synthesis of 2-aminothiophene is troublesome although it is a rather simple heterocycle. In this work, an early report was newly developed as a basis for the efficient synthesis of thiophene-ring-containing chromophore components for photonic polymers. 2-Amino-5-nitrothiophene and 2-amino-3,5-dinitrothiophene
2-氨基噻吩衍生物是本合成的关键中间体。已知2-氨基噻吩的合成是麻烦的,尽管它是相当简单的杂环。在这项工作中,新近开发了一份早期报告,作为有效合成光子聚合物含噻吩环的生色团组分的基础。以优异的产率合成了2-氨基-5-硝基噻吩和2-氨基-3,5-二硝基噻吩。重氮化后,将2-氨基噻吩衍生物直接用N处理-苯基二乙醇胺提供二电子推挽化合物。还制备了类似的苯乙烯基化合物。所有这些生色团分子在分子的一端上都具有可聚合的羟基。这些化合物目前在制造高度敏感的非线性光学聚合物材料中显示出令人感兴趣的潜力。
