Reported is the condensation between o‐arylenediamines and nitroarenes enabled by a cooperative action of acid and base, providing a direct entry to 2‐aryl‐2H‐benzotriazoles. The potential practicability of this methodology was demonstrated by 100 mmol‐scale reactions and the synthesis of serotonin/dopamine receptor ligand and human growth hormone.

electron microscopy (SEM), which showed the influence that the peripheral substitution has on the morphology of the aggregates. For example, methoxy-substituted benzotriazoles self-assemble into thick and crystalline needle-like structures. However, the unsubstituted triazoles give rise to flower-like aggregates. Interestingly, the aggregates formed by benzotriazole 1c exhibit waveguide properties.
通过微波辐射下的Sonogashira偶联反应合成了T型2 H-苯并[ d ] [1,2,3]三唑衍生物。进行DFT计算是为了了解结构与属性之间的关系,这一方面对于合理设计用于光电应用的有机自组装件至关重要。浓度依赖性1H脉冲场梯度自旋回波(PFGSE)NMR光谱和UV / Vis分光光度法表明溶液中没有单分子聚集的趋势。相反,在固态下,这些化合物形成有组织的聚集体,并通过扫描电子显微镜(SEM)对其进行了研究,结果表明外围取代对聚集体的形态有影响。例如,甲氧基取代的苯并三唑自组装成厚的和结晶的针状结构。然而,未取代的三唑产生花状聚集体。有趣的是,由苯并三唑1c形成的聚集体表现出波导特性。
