Rhodamine derivatives having selectivity for Au3+ and method for monitoring Au3+ using the same

摘要

The invention of gold ions detected by fluorescence sensor and it includes a rhodamine derivatives having a gold ion-selective relates to a process , more specifically, rhodamine derivatives and gold ions to gold ions easily by measuring the increase in fluorescence intensity generated by selectively coupling and can be rapidly detected . Further , it is indicated an optional bond is changing colorless to pink colorimetric change of the rhodamine derivative , and gold ions can be detected with the naked eye for the presence of gold ion .
