substituted Δ3‐1,2,3‐triazolines can be prepared by reaction of triarylvinyl Grignard reagents with functionalized organic azides. The heterocycles are fluorescent in the solid state, and—depending on the substituents—they can display aggregation‐induced emission. Upon oxidation, the triazolines form stable radical cations with altered photophysical properties. Therefore, they represent rare examples of
高度取代的Δ 3 -1,2,3- triazolines可以通过用官能化有机叠氮化物triarylvinyl格氏试剂的反应来制备。杂环在固态时是发荧光的,并且取决于取代基,它们可以显示聚集诱导的发射。在氧化时,三唑啉形成具有改变的光物理性质的稳定的自由基阳离子。因此,它们代表了具有内在电致变色行为的固态发射器的罕见示例。
