For instance, solar cells based on poly(2,7-carbazole) and poly(thienopyrroledione) derivatives have revealed power conversion efficiencies up to 8-9 %. This class of materials could lead to printable and flexible photovoltaic devices as well as other plastic electronic devices. Along these lines, we will describe novel synthetic methodologies for a simple and \u201cgreen\u201d preparation of such well-defined conjugated polymers. These new synthetic methods are based on direct (herero)arylation reactions that allow the formation of carbon-carbon bonds between heteroarenes and aryl halides. They do not require organometallic intermediates thereby significantly reducing both synthetic steps, metallic by-products, and cost. They even make possible the synthesis of conjugated polymers that were unknown up to now.\u0026nbsp;\u003C\/p\u003E\u003Cp align=\u0022left\u0022\u003E\u003Cstrong\u003EAbout Mario Leclerc\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EMario Leclerc was awarded a Ph.D. in chemistry from Universit\u00e9 Laval, Quebec City, Canada, in 1987, under the guidance of Prof. R.E.

Predicting the impact of structure on properties requires a detailed understanding of molecular interactions and dynamics at an atomistic level, as well as computationally efficient means of translating structural information into optoelectronic properties at a macroscopic, device relevant level. Although predictive models are not yet available except for simple systems, significant progress has been made toward this goal, making use of multi-scale modeling techniques, coarse graining approaches, and structural measurements of model material systems.\u0026nbsp; In this talk we will review methods used to simulate the structure \u2013 property relationship in organic semiconductors, and will present combined experimental and theoretical studies of a number of applications relevant systems including disordered and multicrystalline molecular and conjugated polymer films. We investigate the use of coarse grained methods to rationalize the electronic properties of such systems. We discuss how these methods may contribute to the design of high performance organic semiconductors.\u003C\/p\u003E\u003Cp align=\u0022left\u0022\u003E\u003Cstrong\u003EAbout Jenny Nelson\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EJenny Nelson is a Professor of Physics at Imperial College London, where she has researched novel varieties of material for use in solar cells since 1989.

Our ability to determine charge transport pathways in organic materials has benefitted from soft x-ray scattering and high resolution transmission electron microscopy. In both cases, long-range correlation of conjugated backbones in high carrier mobility polymers is observed providing a clear connection between morphology and charge transport. We have also discovered the existence of quadrites in donor-acceptor polymers suggesting a strategy for future materials design.\u0026nbsp; These advances suggest future avenues for new applications for organic semiconductors.
