Abstract
A novel colorimetric sensor based on BMPA derivative was designed and synthesized. The sensor displayed high selective and sensitive recognition of Cu2+in aqueous DMSO solution via an obvious color change from yellow to pink. The color change can be attribute to form a complex with Cu2+with C=O and N-H bonds. Based on this principle, an analytical method was developed and successfully used in the determination of the copper content in actual sample.
