Trace vapor detection of chemical threats using organic nanofibril optoelectronic sensors

摘要：

　　Organic nanofibers fabricated from pi-conjugated molecules possess one-dimensional (1D) confined optical and electronic properties along the long-axis of nanofiber.Particularly,the extended intermolecular pi-pi stacking enables 1D enhancement of long-range charge transport and exciton migration,which combined make the nanofibril materials unique building blocks for optoelectronic sensors and nanodevices.In this talk,we will discuss our recent progress in the fabrication of high quality nanofibers from various organic molecules and the wide applications in optoelectronic sensing of nitro-based explosives,organic amines,and other chemical reagents that are of great concern of security,environment and health.
