  Sulfonyl rhodamine hydrazide: A sensitive and selective chromogenic and fluorescent chemodosimeter for copper ion in aqueous media

  摘要：

  A novel sulfonyl rhodamine hydrazide chemodosimeter displayed highly selective and sensitive recognition of Cu2+ in aqueous media via colour change from colorless to pink The colour change that occurred as a result of complexation with Cu2+ can be attributed to spirolactam ring-opening and hydrolysis of the hydrazide unit to afford C I Acid Red 52 (Rhodamine B) in the presence of Cu2+ An analytical method was developed and successfully used for the determination of the copper content in a sample (C) 2010 Elsevier Ltd All rights reserved
