have synthesized a series of ethynylated phenazines and their bis-triazolyl cycloadducts to serve as metal ion sensors. Binding of metal ions is achieved through coordination to the phenazine nitrogen atom and the triazole ring. To allow metal sensing in aqueous solution, the triazole units are substituted with water-soluble ethylene glycol chains. These phenazine cycloadducts exhibit a selective affinity
我们合成了一系列乙炔化吩嗪及其双三唑基环加合物,以用作金属离子传感器。金属离子的结合是通过与吩嗪氮原子和三唑环配位而实现的。为了在水溶液中感应金属,三唑单元被水溶性乙二醇链取代。这些吩嗪环加合物对结合银离子表现出选择性亲和力。卤代类似物的检测显示了带隙的降低以及吸收和发射光谱中相应的红移。这些卤素的吸电子性质也导致吩嗪环加合物的金属结合活性显着降低。
