Rhodamine thiospirolactone. Highly selective and sensitive reversible sensing of Hg(ii)
Literature Information
Zhen-Hua Qian, Hong Zheng, Bing-Yuan Su, Zhi Lan, Jin-Gou Xu
A novel rhodamine thiospirolactone chemosensor 1 was found to develop prominent absorbance and fluorescence enhancements in the presence of Hg2+ in aqueous solution and this was suggested to result from the thiospiro ring opening induced by Hg2+ binding.
