Abstract
A novel sensing material based on pyrene doped polyethersulfone worm-like structured thin film is developed using a facile technique for detection of nitroaromatic explosive vapours. The formation of π-π stacking in the thin fluorescent film allows a highly sensitive fluorescence quenching which is detectable by the naked eye in a response time of a few seconds.
摘要
一种基于芘掺杂聚醚砜蠕虫状结构薄膜的新型传感材料，通过一种简单的技术被开发出来，用于检测硝基芳香族爆炸物蒸气。在薄膜荧光体中形成的π-π堆积，允许通过肉眼在几秒钟的响应时间内检测到高灵敏度的荧光猝灭。
