标题：EXP-SA：纳米纤维膜的双重传感爆炸物检测PI姓名：Ling Zang机构：南伊利诺伊大学卡本代尔分校提案编号：0730667这项研究将建立在独特的分子组装技术开创了PI的实验室。通过控制荧光材料的纳米级形态，他们已经证明了有效的气相爆炸物检测是独立的膜厚度。通过修饰分子结构和改进组装的亚芳基-亚乙炔基大环（战神）的制备，它们可以优化基于荧光猝灭的感觉响应。还提出了一种替代的转导机制，其依赖于测量材料中的电导率变化。

TITLE: EXP-SA: Nanofibril Films for Dual-Sensing Explosives DetectionPI name: Ling ZangInstitution: Southern Illinois University at Carbondale Proposal Number: 0730667This research will build upon unique molecular assembly techniques pioneered in the PIs' laboratories. By controlling the nanoscale morphology of fluorescent materials, they have demonstrated efficient vapor phase explosives detection that is independent of film thickness. By modifying the molecular structure and improving fabrication of the assembled arylene-ethynylene macrocycles (AREs), they can optimize the fluorescent quenching-based sensory response. An alternative transduction mechanism is also proposed which relies on measuring conductivity changes in the materials.
