摘要: 报道了一种中位-联吡啶取代的4,4-二氟-4-硼-3a,4a-二氮-s-因达省(简称BODIPY) 1的合成与离子识别性能。化合物1在加入Cu2+后,荧光被猝灭,加入HPO42-能使这种荧光恢复,而且对Cu2+和HPO42-有着很高的专一性识别。表明化合物1是一种新型的荧光逻辑门探针。 |

Abstract: A meso-bipyridine substituted 4, 4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) 1 has been synthesized and its response for metal cations and anions has been investigated. 1 shows fluorescence “turn-off” response toward Cu2+. Further addition of HPO42- regenerates the fluorescence intensity, indicating that 1 can be used as a logic gate with high selectivity for Cu2+ and HPO42- ions. |
Keywords: boron-dipyrromethene fluorescent logic gate ion recognition Cu2+ HPO42- |
