光可切换化合物可以通过光在两种异构体之间可逆地切换,继续引起广泛应用的显着关注。偶氮杂芳烃代表了一种相对较新但研究不足的光开关类型,其中传统偶氮苯类中的一个芳环已被五元杂芳环取代。初步研究表明,偶氮杂芳烃——特别是芳基并吡唑——具有优异的光开关特性(定量开关和长 Z 异构体半衰期)。在这里,我们提出了一项系统的计算和实验研究,以阐明芳基并吡唑的长热半衰期和优异的可寻址性的起源,并应用这一理解来确定各种可比较的偶氮杂芳基光开关的重要结构-性质关系。我们通过杂环的调节,鉴定了具有 Z 异构体半衰期从几秒到几小时、到几天甚至几年以及可变吸收特性的化合物。构象可能在决定这些性质方面发挥着最大的作用:异构化半衰期最长的化合物采用 T 形基态 Z 异构体构象并通过 T 形异构化途径进行,而对于具有最长异构化半衰期的化合物,实现了最完整的光开关具有扭曲(而不是 T 形)的 Z 异构体构象。通过平衡这些因素,我们报告了一种新的偶氮吡唑

(1) has been obtained via nitration of 3,5‐dinitropyrazole with mixture of sulfuric and nitric acids. Compound 1 reacts with excess ammonia and aliphatic amines, in the presence of bases with NH‐azoles, phenols, thiols, and triflouroethanol at mild conditions in water. All these reactions occur as the nucleophilic substitution of the nitro‐group at position 4 in 1 affording 4‐R‐3,5‐dinitropyrazoles.

environmentally friendly synthesis of nitropyrazoles in good yields using silica‐bismuth nitrate and silica‐sulfuric acid‐bismuth nitrate at room temperature for the first time. The relatively non‐toxic nature, ease of handling, easy availability, and low cost make the present procedure attractive for the nitration of a wide variety of diazoles in the drug and pharmaceutical industries.
