Abstract

Paper highlights advances in design of fluorescent sensors for solvent vapors with boron-dipyrromethene (BODIPY) as a model active component. The present study demonstrates that BODIPY-based fluorescent materials could be successfully utilized for detection of benzene and acetone in gas phase. Concentration of luminophore was found to affect sensory response to benzene (up to 3-fold increase in adjusted conditions). At the same time, sensory response to acetone is concentration-independent, suggesting different underlying response mechanisms and allowing to tune selectivity with choice of concentration. Detection limits achieved for sensory materials are 1.2·10⁴ mg/m³ for acetone and 0.94·10⁴ mg/m³ for benzene. Ultimately, obtained sensor materials could be completely regenerated without need for inert gas purge.

基于 BODIPY 的荧光传感器材料对空气中的丙酮和苯具有聚集驱动选择性

论文重点介绍了以硼-二吡咯并二酮（BODIPY）为模型活性成分的溶剂蒸汽荧光传感器的设计进展。本研究表明，基于 BODIPY 的荧光材料可成功用于检测气相中的苯和丙酮。研究发现，发光体的浓度会影响对苯的感官反应（在调整条件下可增加 3 倍）。同时，对丙酮的感官反应与浓度无关，这表明潜在的反应机制不同，可以通过选择浓度来调整选择性。感应材料的检测限分别为：丙酮 1.2-104 毫克/立方米，苯 0.94-104 毫克/立方米。最终，获得的传感器材料可以完全再生，无需惰性气体吹扫。
