A "turn-on" fluorescent and colorimetric chemosensor (RBS) for Pd(2+) has been designed and synthesized through introduction of sulfur as a ligand atom to Rhodamine B. RBS exhibits high selectivity (freedom from the interference of Hg(2+ )in particular) and sensitivity toward Pd(2+) with a detection limit as low as 2.4 nM. RBS is also a reversible sensor, and it can be made into test paper to detect Pd(2+) in pure water. Compared to the chemosensors that introduced phosphorus to Rhodamine to detect Pd(2+), RBS can be synthesized more simply and economically.
通过将硫作为配体原子引入罗丹明B，设计并合成了一种用于检测Pd(2+)的“开启型”荧光和比色化学传感器（RBS）。RBS对Pd(2+)表现出高选择性（尤其不受Hg(2+)干扰）和高灵敏度，检测限低至2.4 nM。RBS还是一种可逆传感器，可制成试纸用于检测纯水中的Pd(2+)。与通过将磷引入罗丹明来检测Pd(2+)的化学传感器相比，RBS的合成更简单、更经济。
