摘要：

Self-assembled molecular nanostructures or organic thin films with well-defined orientation, conformation, and two-dimensional (2D) organization on surfaces have great potential in organic electronics, and molecular nano-devices. Their interfaces to substrates (dielectric or conducting electrodes) and of the organic heterojunctions have the crucial impact on the device performances. In particular, significant improvement on the power conversion efficiency of organic photovoltaic devices, constructed from organic p-n or organic-inorganic heterojunctions, relies on the thorough understanding as well as effective engineering of those interface properties. In this talk I will briefly introduce our work in these fields, using synchrotron-based photoemission spectroscopy (PES), near-edge x-ray absorption spectroscopy (NEXAFS) and low-temperature scanning tunneling microscopy (LT-STM) to investigate the molecular and organic-electronics and graphene related interface problems, including self-assembled molecular nanostructure arrays, interface dipole formation, interface energy level alignment, supramolecular packing and molecular orientation.
