Multi-functional rhodamine 6g derivative attached with 2-thiazolylethyl amine and preparation method and use thereof

Abstract

A multi-functional rhodamine 6G derivative attached with 2-thiazolylethyl amine, a preparation method and use thereof are provided. The multi-functional rhodamine 6G derivative attached with 2-thiazolylethyl amine is prepared by a one-step method with rhodamine 6G and 2-thiazolylethyl amine as raw materials. In the present invention, a new multi-functional rhodamine 6G derivative RGET is synthesized by a one-step method. RGET is useful as a highly selective and sensitive Fe3+ spectroscopic probe, the detection limit for Fe3+ is 2.1 nM, and the fluorescence intensity is increased by 541 times by Fe3+. Moreover, RGET has antibacterial performances comparable to those of commercial bleach for Gram-positive bacteria and Gram-negative bacteria and is very lowly cytotoxic, thus having bright application prospects in the fields of environment protection and life sciences.
