Abstract
A novel thiopiperazine fluorescent probe——1,4-bis【4-{ [4-( trifluoromethyl) quinolin-2-yl]thio} butyl】piperazine( 4) was synthesized by a four-step reaction from 4-( trifluoromethyl) quinolin-2( 1H)-one and piperazine. The structure was characterized by1H NMR and LC-MS. The selectivity of 4 on Cu2+ in methanol was investigated by UV-Vis and FL. The results showed that λ max of 4 was 396 nm. 4 exhibited selectivity for Cu2+in 1. 0 × 10- 7mol·L- 1~ 1. 0 × 10- 4mol·L- 1.
