In the present work we have demonstrated a supramolecular approach for ratiometric luminescence sensing of nitroaromatic explosive compounds (NAEs) by employing a red luminescent Eu(III) complex and a green luminescent Pt(II) complex with in a Triton X-100 surfactant based micellar host in water. The Eu-complex gets entrapped inside micellar core whereas the Pt-C2 remains grafted on the surface of the spherical micelles due to their structural amendments and thus facilitates preferential interaction of Pt-C2 with NAE molecules mainly through π-π interaction. The presence of explosive traces quenches the green emission (508-545 nm) of Pt-complex whereas the red emission (614 nm) of Eu-complex remains unaffected. The strategy demonstrates first report of two independent luminophore based ratiometric sensing in water using a micellar host.

水中硝基芳香族炸药的比例发光传感的超分子策略

在目前的工作中，我们已经证明了超分子方法，用于在基于Triton X-100表面活性剂的胶束中使用红色发光的Eu（III）配合物和绿色发光的Pt（II）配合物，用于硝基芳香族爆炸化合物（NAE）的比例发光传感。主机在水中。Eu-复合物被困在胶束核心内，而Pt-C2由于其结构修饰而保留在球形胶束表面，因此主要通过π-π相互作用促进了Pt-C2与NAE分子的优先相互作用。爆炸痕迹的存在使Pt络合物的绿色发射（508-545 nm）猝灭，而Eu络合物的红色发射（614 nm）保持不受影响。该策略展示了使用胶束宿主在水中基于两个独立发光体的比率式传感的首次报道。
