报告人简介：Charl F. J. Faul is Professor of Materials Chemistry and Director of Graduate Recruitment for the School of Chemistry, University of Bristol, UK. He received his PhD from the University of Stellenbosch, South Africa, in 2000. After 4 years as senior scientist at the Max Planck Institute of Colloids and Interfaces (Potsdam, Germany), he moved to Bristol in 2005. He held a visiting professorships at the Helsinki University of Technology (2006 – 2010), the Chinese Academy of Sciences (National Centre for Nanoscience and Technology, Beijing (2012)) and is Adjunct Professor at the Department of Chemistry, Tsinghua University (Beijing, China) since November 2013.
He is co-Principal Investigator and member of the Management Board of the £12M EPSRC-funded centre for doctoral training, the Bristol Centre for Functional Nanomaterials (BCFN). As Director of Graduate Recruitment he is responsible for and has oversight of all graduate recruitment activities within the School of Chemistry.
Prof. Faul is a synthetic materials chemist with a multidisciplinary international research group focussing on soft functional nanostructured materials. His activities range from fundamental to application-driven areas, where ionic self-assembly and the design, synthesis and application of soft, electroactive nanomaterials are explored. Applications are actively pursued in the areas of energy (CO2 capture, storage, conversion), and electroactive materials and devices (nanowire-based field-effect transistors, actuators for robotics, and 3D-printed addressable photonic structures).

报告摘要：Aniline-based materials have a very long history in the field of conducting organic materials. The development of new synthetic and theoretical methodologies, combined with advances in instrumentation and self-assembly approaches to materials, are now are yielding a next generation of materials for electronic and photonic applications.
Starting from sub-monolayer level, we have recently imaged, for the first time, the predicted conformational isomerism of various oligo(aniline)s using ultra-high vacuum (UHV) scanning tunnelling microscopy.  The observed structures were not only corroborated by TD-DFT calculations, but also provide insight into the role oxidation state plays during self-assembly.  Utilising these insights, we prepared ultra-smooth 20nm-thin films of doped oligo(aniline)s, and developed a conductive-AFM redox-writing (cAROW) technique to locally address and image changes in oxidation state (and conductivity).  We combined our cAROW technique with high-speed AFM technology, and could write arbitrary shapes at high speed and with high precision.
These recent studies provide further support for our detailed investigations into the supramolecular organisation of oligo(aniline) self-assembled nanowires in aqueous media.[4] Additionally, these activities now act as a platform for our current TD-DFT studies to accurately model spin and doped states, as well as the development of porous aniline-based materials for CO2 capture and storage.
With our newly gained fundamental understanding of aniline-based materials, we are now exploring new applications, including addressable photonic structures
