Abstract

A fluorescent organic small molecule, hexaphenylsilole (HPS), has been used as a sensing material, while a HPS/polymethyl methacrylate composite film with a lotus leaf like structure is prepared by a simple electrospin method. The film shows high stability and excellent sensitivity for the metal ions Fe(3+) and Hg(2+), respectively. The special surface morphology containing micro-/nanocomposite structure is attributed to the exhibition of these unusual properties.

摘要

一种荧光有机小分子六苯基硅杂环戊二烯（HPS）被用作传感材料，同时通过一种简单的静电纺丝方法制备了具有荷叶状结构的HPS/聚甲基丙烯酸甲酯复合薄膜。该薄膜分别对金属离子Fe(3+)和Hg(2+)表现出高稳定性和优异的灵敏度。包含微/纳米复合结构的特殊表面形态归因于这些异常特性的展现。
