题 目：Unique Optoelectronic Properties of Organic Nanofibers: Material Design and Engineering at Nanoscale
报告人：Prof. Ling Zang (University of Utah)
Organic nanofibers have gained increasing interests, largely due to the unique optoelectronic properties and potential applications in various nanodevices in competition with the inorganic counterparts. Nanofibers fabricated from rigid, planar aromatic molecules possess one-dimensional (1D) optical and electrical properties along the long-axis. Such 1D dominant properties include long-range charge transport and exciton migration, making the nanofibers unique building blocks for optoelectronic sensor devices. In this talk, we will discuss our recent progress in the fabrication of high quality nanofibers from various building block molecules and the applications in vapor detection of explosives, drugs and other chemicals, which are of great interest to security, environment and health concerns.
