Purdue University School of Chemical Engineering Graduate seminar series Prof. Yueh-Lin Loo Theodora D. '78 & William H. Walton III '74 Professor in Engineering Princeton University "Accessing Polymorphism and Tuning Molecular Orientation in Solution-processed Organic Semiconductors" September 30, 2014 9:00-10:15 a.m. FRNY G140 Reception at 10:15-10:45 a.m. in Henson Atrium Abstract: Though both the molecular orientation and crystal structure of molecular semiconductors are known to impact charge transport in thin-film devices, controllably accessing different polymorphs and tuning both the in-plane and out-of-plane molecular orientations remain challenging, requiring careful selection of film deposition conditions, film thickness, and substrate chemistry. Without necessitating any specification of these parameters, we have been able to impose specific polymorphs and/or preferential molecular orientation through post-deposition processing. In the case of contorted hexabenzocoronene (HBC), we can access two distinct polymorphs and independently vary the distributions of its out-of plane molecular orientation. Starting with a thermally evaporated amorphous HBC film, thermal and solvent-vapor annealing induces the thin film to crystallize into distinct polymorphs; we can further transform between the polymorphs with subsequent rounds of processing. Because the molecular orientation distribution is primarily determined during the first processing step, subjecting already crystalline thin films to different post-deposition processing conditions allows us to access different polymorphs without altering the molecular orientation distribution, thus enabling us to decouple the influence of each on charge transport. In the case of solution-processable triethylsilylethnyl anthradithiophene (TES ADT), we have been able to exploit its differential crystallization rates on substrates having different surface energies to guide the in-plane growth direction of neighboring crystals. The systematic engineering of solely low- and high-angle grain boundaries between neighboring crystals have allowed us to elucidate their relative contribution to charge transport. Bio: Lynn Loo is the Theodora D. '78 & William H. Walton III '74 Professor in Engineering at Princeton University. In the Chemical & Biological Engineering Department, her research emphasizes the structure development of complex materials for low-cost, lightweight and scalable plastic circuits and solar cells. With her recent stint at NewWorld Capital Group, a private equity firm that focuses on investments in environmental opportunities, Lynn's research has expanded to include macro-energy-systems analysis and carbon balance for processes that generate liquid fuels. As the Associate Director of External Partnerships at the Andlinger Center for Energy and the Environment, Lynn leads the Princeton Effiliates Partnership that promotes teacher-student-practitioner interactions and fosters collaboration between the private sector and faculty on campus. Lynn received her PhD from Princeton University in 2001. She is a fellow of the American Physical Society and has been recognized as a Top 100 Young Innovator by MIT's Technology Review, with the Alan P. Colburn Award from the American Institute of Chemical Engineers, the John H. Dillon Medal of the American Physical Society and Sloan and Beckman Fellowships.

Purdue University School of Chemical Engineering Graduate seminar series Dr. A.N. Sreeram Corporate Vice President of Research & Development The Dow Chemical Company "Winning Products Demonstrate the Strength and Breadth of Innovation at Dow Chemical" Thursday, October 2, 2014 9:00-10:15 a.m. FRNY G140 Reception at 10:15-10:45 a.m. in Henson Atrium Abstract: Winning in the marketplace is critical for a company's success. In addition to the financial metrics on innovation that Dow tracks internally, awards from external (to Dow) independent organizations are one way that innovation is recognized and highlighted to the public. Recognition received by Dow products and its people demonstrates the strength and breadth of innovation at Dow Chemical. Five products were recently named 2014 R&D 100 Award winners, recognized as some of the most innovative products of 2013. Last year we were awarded our ninth Presidential Green Chemistry Award, recognizing our commitment to products that improve our world. Several successful Dow products that are also award winners will be highlighted. The story behind the innovations will be shared, highlighting how Dow's culture and capabilities combine to bring new products to market. Rigorous R&D metrics that prioritize resources for maximum impact, a focus on efficiency, including unrivaled high-throughput capabilities, and collaboration on technology and with brand-owners to deliver real-world solutions all contribute to our success. Actual impact in the marketplace with products that improve the world is the ultimate goal. Awards validate that our efforts are yielding both innovative and impactful products. Bio: Dr. A.N. Sreeram is Corporate Vice President of Research & Development for The Dow Chemical Company. Prior to assuming this role, he served as Vice President of R&D for Dow Advanced Materials. Sreeram originally joined Dow in June 2006 as Vice President of Core R&D. Prior to joining Dow, he served as the Global Technology Director and Chief Technology Officer for DuPont Electronic Technologies. Prior to this, he served as Vice President of Worldwide Technology for Cookson Electronics, and before that he led the Electronic and Flat Display Program for Sarnoff Corporation. Sreeram, who holds more than 20 U.S.-issued patents, earned his doctorate degree in 1995 from the Department of Materials Science & Engineering at Massachusetts Institute of Technology (M.I.T.), and his master's degree in Glass Science from Alfred University in New York. He is also a graduate of the ceramics engineering program from the Indian Institute of Technology - BHU in Varanasi, India.
