A new chelating diaryloxadiazole probe, oxazid displayed emission red shift and 16-fold emission enhancement upon binding with Zn2+ in buffered condition, while competing Cd2+, Ca2+, Mg2+, and several potentially quenching metal ions posed no significant optical interferences. Experimental evidences indicated 1:1 complexation, and the computational work revealed formation of a stable octahedral geometry.
一种新的螯合二芳二唑探针 oxazid 在缓冲条件下与 Zn2+ 结合后显示出发射红移和 16 倍的发射增强,而与之竞争的 Cd2+、Ca2+、Mg2+ 和几种潜在的淬灭金属离子则没有明显的光学干扰。实验证据表明,二者的络合比例为 1:1,而计算工作显示,二者形成了稳定的八面体几何结构。
