A realistically newly designed Cu ion specific fluorescent chemodosimeter has been synthesized from α,α'-(,)-bis(benzylidene)cyclohexanone having a fused spiro-dihydropyran moiety characterized by 2D NMR and X-Ray Crystallographic study. It also demonstrates an irreversible, instant direct visualisation by unaided eye chemosensing property in aqueous buffer (pH 7.4) with a colour change from yellow to orange upto 0.3 × 10 M.

独特的基于稠合螺二氢吡喃的化学剂量计的合成和表征,用于通过“开启”模式选择性视觉和荧光检测水介质中的 Cu2+ 离子



由具有稠合螺环二氢吡喃部分的 α,α'-(,)-双(亚苄基)环己酮合成了一种全新设计的 Cu 离子特异性荧光化学剂量计,并通过 2D NMR 和 X 射线晶体学研究进行了表征。它还通过在水性缓冲液(pH 7.4)中的肉眼化学传感特性展示了不可逆的、即时的直接可视化,颜色变化从黄色到橙色高达 0.3 × 10 M。
