A highly sensitive and selective turn-on fluorescent chemosensor for palladium based on a phosphine-rhodamine
1School of Materials Science & Engineering, Tianjin University of Technology, China.
Abstract:
A fluorescent chemosensor with high sensitivity and selectivity for palladium species based on a conjugate of phosphine and rhodamine B has been developed. The chemosensor showed an excellent palladium selectivity with a detection limit down to the 10(-9) M range, which is lower than the WHO limit for palladium content in drug chemicals.
