Brian Reeves Presents: Functional Fluorinated Materials for Organic Electronics

Friday March 30th, 2018 at 4:00 PM in Chemistry A101

Research seminar abstract Organic photovoltaic (OPV) devices and organic light emitting diodes (OLED) have shown significant promise as cost effective alternatives to their inorganic competitors. Within the OLED field, there is currently an effort to replace iridium (III) sensitizers with cheaper copper(I) alternatives. One issue that needs to be overcome is the Jahn-Teller distortion in […]

Tara Van Surksum Presents: Unraveling Fundamental Hydrocarbon Plasma Chemistry & Film Deposition Processes

Wednesday March 28th, 2018 at 4:00 PM in Chemistry A101

Research seminar abstract Diamond-like carbon (DLC) films have numerous potential applications because of their appealing mechanical and electronic properties (e.g., hardness, thermal conductivity, and high electrical resistance).[1-4]  Plasma enhanced chemical vapor deposition (PECVD) is a widely used technique in the production of DLC films, but to date, little is known about the underlying molecular-level chemistry […]

Dick Zare Presents: Microdroplet Chemistry, a New Frontier

Wednesday March 7th, 2018 at 4:00 PM in Chemistry A101

My research group has been studying chemical reactions in microdroplets and comparing the findings with the behavior of the same reaction in bulk solution.  Our detection method has primarily been high-resolution mass spectrometry.  Two different experimental setups are employed, one involving fusing together two streams of microdroplets (shown in Fig. l, the panel on the […]

Romeo Portillo Presents: Investigations into the electronic structure of d3 transition metal complexes and their relevance to photocatalysis

Tuesday March 6th, 2018 at 4:00 PM in Chemistry A101

Research seminar abstract The electronic structures of inorganic complexes can provide insight into the reactivity of ground and excited state species in catalytic systems. Recent advances in Cr-photocatalysis have demonstrated unique photocatalytic properties when compared to other transition metal photocatalysts. To understand what role(s) these Cr species share in photocatalysis, we have investigated several heteroleptic […]

Colin Brook Presents: Improvement of photooxidative stability of fluorinated donor-acceptor blends in organic photovoltaics

Friday March 2nd, 2018 at 4:00 PM in Chemistry A101

Research seminar abstract In this work, we seek to improve the long-term stability of organic photovoltaic (OPV) active layers under white light illumination in air through the use of perfluoroalkylfullerene acceptors. The rates of irreversible photobleaching of blends of donor polymers and fullerene acceptors were found to correlate well with the electron affinity of the […]

Angela Hanna Presents: Investigations of Fundamental Plasma Chemistry and Surface Interactions

Wednesday February 28th, 2018 at 4:00 PM in Chemistry A101

Research seminar abstract With increasing concern about environmental health and climate change, there is a greater need for fundamental studies investigating the reactivity of pollutant species. Improving the effectiveness of substrates used in vehicular emissions abatement hinges on the ability to discern the contributions of gas-phase species in surface reactions.  Plasma assisted catalysis (PAC) provides […]

Tuesday February 27th, 2018 at 4:00 PM in Chemistry A101

Pahl, P.; Schwarzenböck, C.; Herz, F.A.D.; Soller, B.S.; Jandl, C.; Rieger B. Core-First Synthesis of Three-Armed Star-Shaped Polymers by Rare Earth Metal-Mediated Group Transfer Polymerization. Macromolecules. 2017, 50, 6569-6576 (DOI: 10.1021/acs.macromol.7b01007)  

Mercouri Kanatzidis Presents: Halide Perovskites: Poor man’s high performance semiconductors

Friday February 23rd, 2018 at 4:00 PM in Chemistry A101

Organic-inorganic hybrid perovskites are a special class of low cost semiconductors that have revolutionized the prospects for photovoltaic and optoelectronics technologies. The inorganic chemistry of this class of materials is fascinating. These compounds adopt the three-dimensional ABX3 perovskite structure, which consists of a network of corner-sharing BX6 octahedra, where the B atom is a divalent metal cation […]
