A new malonamide fluoroionophore possessing two pyrene moieties was synthesized. This bispyrene exhibited the fluorescence of the pyrene monomer (lambda(em) = 395 nm) and intramolecular excimer (lambda(em) = 467 nm) emissions. The designed derivative showed the excellent ion sensing ability to Cu2+. The "on-off-off" and "off-on-off" fluorescence responses were demonstrated by the addition of the variable Cu2+ concentration. The utilization of the dual off/on responses could apply to the estimation of the rough Cu2+ concentration.
合成了一种含有两个芘基团的新型丙二酰胺氟离子载体。这种双芘显示出芘单体的荧光（发射波长λ(em)=395nm）和分子内激基缔合物的荧光（发射波长λ(em)=467nm）。所设计的衍生物对Cu2+表现出优异的离子传感能力。通过添加不同浓度的Cu2+证明了“开-关-关”和“关-开-关”荧光响应。利用这种双关/开响应可用于粗略估计Cu2+浓度。
