Based on boron-dipyrromethene (BODIPY), taking 2-hydroxy-N-(2-hydroxyphenyl)benzamide as recognition site, a new fluorescent probe HHPBA-BODIPY aimed at sensitively detecting Cu ions was designed, synthesized and characterized.The emission spectra of HHPBA-BODIPY exhibited an intensive green fluorescence around 510 nm, with a maximum absorption near 500 nm. When Cu ions are present, the fluorescence at 510 nm can be quenched with a good linearity between the copper ion concentrationand the fluorescence intensity and the detection limit is 0.35 μM. HHPBA-BODIPY is also selective toward Cu, while other metal ions show no interfere except Fe and Cr ions. In addition, HHPBA-BODIPY also proved efficient to detect Cu in water samples which offers the possibility to detect trace amount of Cu for environmental monitoring.

基于硼二吡咯亚甲基（BODIPY），以 2-羟基-N-（2-羟基苯基）苯甲酰胺为识别位点，设计、合成并表征了一种新的用于灵敏检测 Cu 离子的荧光探针 HHPBA-BODIPY。HHPBA-BODIPY 的发射光谱在 510nm 左右表现出强烈的绿色荧光，最大吸收在 500nm 附近。当存在 Cu 离子时，510nm 处的荧光可以被淬灭，铜离子浓度与荧光强度之间具有良好的线性关系，检测限为 0.35μM。HHPBA-BODIPY 对 Cu 具有选择性，而其他金属离子除 Fe 和 Cr 离子外没有干扰。此外，HHPBA-BODIPY 还能够有效地检测水样中的 Cu，为环境监测中痕量 Cu 的检测提供了可能。铜离子；BODIPY；荧光探针。
