摘 要：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.
