Novel rhodamine and quinoline-functionalized nano film was prepared by copolymerization and electrospinning. Propenyl monomer of rhodamine and quinoline was synthesized and then copolymerized with methyl methacrylate via solution polymerization. This prepared copolymer was electrospun into nano film, as a solid-state sensor, which exhibits highly selective recognition of Fe³⁺ ions over various environmentally and biologically relevant metal ions and anions with a distinct color change from colorless to pink in very fast response time (<1 min). The sensor can detect Fe³⁺ quantitatively in concentration range of 100–2000 μM, and the calculated low detection limit (LOD) value could be 1.19 μM for Fe³⁺. As the resultant product, the Fe³⁺-contaminated nano film showed recovered color change by extra addition of pyrophosphate P₂O₇⁴⁻ (PPi) solution. It was found that the absorption intensity at 564 nm of the Fe³⁺-contaminated nano film linearly decreases with PPi concentration from 50 to 3000 μM with LOD value of 1.75 μM. In addition, both the nano films before and after Fe³⁺-contaminating are reusable for the detection of Fe³⁺ and PPi, respectively.

通过共聚和静电纺丝制备了新型罗丹明和喹啉官能化纳米薄膜。合成了若丹明和喹啉的丙烯基单体，然后通过溶液聚合与甲基丙烯酸甲酯共​​聚。将此制备的共聚物静电纺丝成纳米膜，作为固态传感器，它对各种环境和生物学相关的金属离子和阴离子表现出高度选择性的识别Fe ³⁺离子，并且在非常快的响应时间内颜色从无色变为粉红色。 （<1分钟）。传感器可以在100–2000μM的浓度范围内定量检测Fe ³⁺，计算出的Fe ³⁺的低检测下限（LOD）值为^1.19μM。作为产物Fe ³⁺被污染的纳米膜通过额外添加焦磷酸盐P ₂ O ₇ ^4-（PPi）溶液显示出恢复的颜色变化。发现被Fe ³⁺污染的纳米膜在564 nm处的吸收强度随着PPi浓度从50到3000μM线性下降，LOD值为1.75μM。另外，污染Fe ³⁺之前和之后的纳米膜都可分别用于检测Fe ³⁺和PPi。
