基于“受体-间隔基-荧光团”[2-(2 '-氨基苯基)苯并恶唑-酰胺-2-吡啶甲基胺]传感器平台的水溶性荧光传感器1显示出对Zn 2+的高灵敏度,在螯合Zn 2+时具有25倍的荧光增强,并且还显示出对Zn 2+的高选择性超过其他金属离子。Zn ~(2+)配合物的X-射线晶体结构表明,酰胺氧(O_2)与2-吡啶甲基胺单元(N_3,N_4)作为受体结合Zn ~(2+)。
A water-soluble fluorescent sensor, 1, based on the "receptor-spacer-fluorophore" [2-(2'-aminophenyl)benzoxazole-amide-2-picolylamine] sensor platform, demonstrates the high sensitivity for Zn2+ with a 25-fold fluorescence enhancement upon chelation to Zn2+ and also exhibits high selectivity to Zn2+ over other metal ions. X-ray crystal structure of Zn2+ complex reveals that the amide oxygen (O2) cooperates with 2-picolylamine unit (N3, N4) as a receptor bind Zn2+.
