moiety, N,N′-(9,10-dioxo-9,10-dihydroanthracene-1,8-diyl)bis(2-(bis(pyridin-2-ylmethyl)amino)acetamide) (1) and N,N′-(9,10-dioxo-9,10-dihydroanthracene-2,6-diyl)bis(2-(bis(pyridin-2-ylmethyl)amino)acetamide) (2), have been successfully synthesized with the overall yields of 61% and 90%, respectively. The structures of both chemosensors 1 and 2 were elucidated using several spectroscopic techniques such
基于蒽醌部分的开启荧光化学传感器,N , N '-(9,10-二氧代-9,10-二氢蒽-1,8-二基)双(2-(双(吡啶-2-基甲基)氨基)乙酰胺) ( 1 ) 和N , N '-(9,10-二氧代-9,10-二氢蒽-2,6-二基)双(2-(双(吡啶-2-基甲基)氨基)乙酰胺) ( 2 ) ,已成功合成,总产率分别为61%和90%。使用多种光谱技术(例如1 H NMR、13 C NMR、2D-NMR、FTIR 和 HRMS)阐明了化学传感器1和2的结构。目标化学传感器1通过开启光致电子转移 (PET)表现出显着的荧光增强,是检测痕量d 10金属离子(例如 Zn( II ) 和 Cd( II ) 离子)的有前途的工具该机制具有快速且高度可重复的信号,对于 Zn( II ) 和 Cd( II )的检测限分别低至 0.408 μM 和 0.246 μM 。
