We present the first example of azide functionalization on the surface of graphene oxide (GO), which preserves thermally unstable groups in GO through the mild reaction with sodium azide in solids. Experimental evidence, by (15)N solid-state NMR and other spectroscopic methods, indicates the substitution of organosulfate with azide anions as the reaction mechanism.
我们首次在氧化石墨烯(GO)表面实现了叠氮化物的功能化,该方法通过固态下温和的叠氮化钠反应保留了 GO 中热不稳定的基团。通过(15)N 固态 NMR 和其他光谱方法的实验证据表明,反应机制为有机硫酸盐被叠氮阴离子取代。
