中文摘要：

合成了罗丹明6G酰肼并研究了各种金属离子对其吸收光谱和荧光光谱的影响,结果表明,罗丹明6G酰肼是一种高选择性汞离子荧光探针.在乙醇/4-羟乙基哌嗪乙磺酸缓冲溶液（PH=7.2,体积比1：1）中,罗丹明6G酰肼本身无荧光,加入汞离子使其在554mn产生强发射,发出明亮的黄绿色荧光.其他常见金属离子,包括重金属离子和过渡金属离子,对汞离子引起的荧光增强无影响.罗丹明6G酰肼还被用于活细胞中汞离子的检测.另外,汞离子能使罗丹明6G酰肼在530mn产生强吸收,溶液由无色变为粉红色.

英文摘要：

Rhodamine 6 G hydrazide （ R 6 GH） was developed as a fluorescent p robe for the specific detection of Hg2＋. The presence of Hg2＋ can induced an enhanced fluorescence response at 554 nm accompanied by a naked-eye visible fluorescent color change from colorless to bright yellowish-green. Other metal ions including heavy and transition metal ions have no effect on the response of R 6 GH to Hg2＋. The probe has been used for imaging of Hg2＋ within living Hela cells with satisfying results. In addition,R6 GH can selectively sense Hg2＋ by a color change from colorless to pink.
