(P.11) Patterning strategies for integration of multifunctional organic/inorganic hybrid structures Shengyang Chen, Ioan Botiz, Paul Stavrinou, Natalie Stingelin Imperial College London shengyang.chen14@imperial.ac.uk Abstract Cross-cutting approaches, where molecular engineering and clever processing are synergistically coupled, allow chemists to tailor complex hybrid systems of various shapes with perfect mastery at different size scales, composition, functionality, and morphology. Hybrid materials with organic/inorganic or bio–/inorganic character represent not only a new field of basic research but also, via their remarkable new properties and multifunctional nature, hybrids offer prospects for many new applications in extremely diverse fields. This potential of hybrid materials is reflected by the fact that many of them are entering a variety of markets. In many cases, hybrid materials are constituted by organic components (molecules) or networks (organic polymers) intimately mixed at the molecular or nanoscopic level with inorganic components, such as metal oxides and metals, metallo-polymers but also phosphates, carbonates, chalcogenides and such derivatives. However, currently, most hybrid materials that find applications in industry are based mostly on the association between metallic and/or ceramic matter, frequently combined with organic molecules or ‘plastics’ of all kinds including bio-components. Here, I will present recent activities to design and develop novel strategies towards highly simplified, robust processing of self-assembled, multifunctional arrays at high yield. I will demonstrate procedures towards self-assembly and patterning of various functional species, including inorganic semiconductors such as ZnO, light-emitting quantum dots, or conducting and/or magnetic nanoparticles (e.g. Au, Cu, Co), with the use of surface relief structures and surface energy patterning strategies to create functional architectures at predefined locations without the need for any lithography steps. The key goal will be to produce a wide range of devices from p-n junctions, photovoltaic cells, electrode arrays with an unprecedented ease of processing without the need for lithographic methods and with a versatility to structure wide-range of inorganic (and inorganic/organic hybrid) materials. Keywords: hybrid materials, patterning, surface relief structure, nano-pinballing
Biography Shengyang Chen graduated from the Beijing University of Chemical Technology with a first class B.Eng. in Polymer Science and Engineering in 2014. His postgraduate study was carried out in Advanced Materials Science and Engineering in Imperial College London where he obtained a Distinction MSc degree. In 2015, he was awarded with Chinese Scholarship Council Scholarship and enrolled in the 4-year Plastic Electronics CDT programme. Now he works with Prof Natalie Stingelin and Dr Paul Stavrinou and his research project mainly focuses on exploiting patterning strategies for integration of multifunctional organic/inorganic hybrid structures; the use of additives for solution processing of phOLEDs and electrochromic active layers. 104
