Liu, Yi published the artcileRapid visual identification of nitroaromatics compounds by aggregation-induced enhanced emission fluorescent assays with a Cd(II)-H3BTT complex, Recommanded Product: 1H-1,2,3-Triazole-4,5-dicarbonitrile, the publication is Sensors and Actuators, B: Chemical (2019), 126623, database is CAplus.
A new type of aggregation induced enhance emission (AIEE) active Cd(II) complex based on novel nitrogen-rich polycyclic ligand 4,5-bis(tetrazol-5-yl)-2H-1,2,3-triazole (H3BTT) and its metal organic gel (MOG) had been synthesized for the first time. The colloid of Cd(II)-H3BTT complex showed obvious AIEE characteristics in binary solvent system of DMF and ethanol, and displayed high sensitivity and selectivity for PA sensing over other nitroaroms. like DNB, TNB and TNT, where the limit of detection had been found as low as 9.3 × 10-7 M. Further, visual colorimetric recognition in colloidal state sensor and coated filter paper were all accomplished by spiking PA in tap water and river water. Interestingly, after being ripened, this colloid could be converted into stable MOG with the AIEE performance inherited, which also shown good fluorescence recognition ability and excellent reusability for the visual colorimetric PA detection. And this regenerated colloid from the MOG storage for a period of time kept the same detection ability for PA as fresh colloid. Finally, the recognition mechanism of PA was confirmed as the counterion-displacement assays by FTIR and UV experiments This novel Cd(II)-H3BTT complex provided a new insight into the design and synthesis of AIEE naked eyes recognized sensor for nitroaroms. with a simple and cheap preparation process, high sensitivity and stable storage.
