In this paper, we have synthesized three kinds of new organic fluorescencereagents: 4CRACP Ⅱ, 4B RACPⅢ. 4IRACP Ⅳ,Its structures were identifiedand fluorescence properties were studied. We find 4CRACP-Ⅱ has more intense fluo-rescence in the weak acid medium。 It reacts with copper(Ⅱ)at pH=5.3 to form fluo-rescenta coplex,λ_(ex)/λ_(em)=310nm/408nm. the detection limit was 0.5ng/g, we discussedthe influence of halogen on  ̄1H-NMR. MS.F.
