This paper discloses efficient synthesis of pyrene-1-carbothioamides and carboxamidesviaFriedel–Crafts reaction of pyrene with isocyanates followed by oxidative desulfuration. The amides display solid-state fluorescence with quantum yields up to 62%, originating from monomers, aggregates or excimers.
这篇论文揭示了通过芴与异氰酸酯进行Friedel-Crafts反应,然后进行氧化脱硫制备吡啶-1-羰硫胺和羧酰胺的高效合成方法。这些酰胺在固态下表现出发光性能,量子产率高达62%,来源于单体、聚集体或激聚体。
