SUMMARY:Houk-Jung Organic Colloquium 247: Daniel T. Gryko
DESCRIPTION:1\,4-Dihydropyrrolo[3\,2-b]pyrrole and Dipyrrolonaphthyridinedione – Novel Building Blocks for Optoelectronics \nAbstract: Recently we have discovered and optimized the first practical synthesis of non-fused pyrrole[3\,2-b]pyrroles via domino reaction of aldehydes\, primary amines\, and butane-2\,3-dione.1 Six bonds are formed in heretofore unknown tandem process\, which gives rise to substituted pyrrole[3\,2-b]pyrroles – the ‘missing link’ on the map of aromatic heterocycles. Unparalleled simplicity and versatility of this one-pot reaction\, non-chromatographic purification and superb optical properties (including strong violet\, blue or green fluorescence both in solution as well as in the solid state)\, brought these molecules from virtual non-existence to the intensively investigated area functional π-systems. The parent 1\,4-dihydro-pyrrolo[3\,2-b]pyrroles served as building block to construct various π-expanded analogs including nitrogen-embedded buckybowl with inverse Stone–Thrower–Wales topology2\,3 and diindolo[2\,3-b:2‘\,3‘–f]pyrrolo[3\,2-b]pyrroles. These compounds constitute the most electron-rich ladder-type heteroacenes known to date – EHOMO was located at ca. −4.6 eV. Recently\, we have proved that the dipyrrolonaphthyridinedione (DPND) core constitutes an excellent scaffold for the design of strongly fluorescent dyes or quadrupolar-type materials with large two-photon absorption (TPA) cross-sections (up to 5\,180 GM).37 These properties result from an unusual arrangement of donor (pyrrole ring) and acceptor (carbonyl group) moieties within the DPND core.

SUMMARY:Jeffrey I. Zink Inorganic Chemistry Seminar 278: Charles H. Wallace
DESCRIPTION:Flyer: Dr. Charles H. Wallace \nTitle: The Role of Chemistry in Advanced Patterning of Semiconductor Devices \nAbstract: The presentation will introduce lithography and advanced patterning to construct transistors and interconnects for semiconductor device manufacturing followed by a discussion of the various inorganic chemicals and materials used in the manufacturing process.  Some of the key topics of discussion will include the scaling of transistors and the role of the minimum resolution of lithography equipment (Rayleigh’s equation).  A summary of historical scaling will be reviewed and a description of future research and development that is required to continue scaling into the future.  The importance of chemistry and impact of chemistry on the manufacturing process and applications will be described.  The introduction of EUV (Extreme Ultraviolet) lithography into the semiconductor patterning process has enabled some simplification of process architecture; however\, has not decreased edge-placement-error (EPE) margin enough to keep up with the pitch scaling requirements.  Chemical selectivity is the most effective way to avoid EPE-caused failures on devices which lead to poor yield.  Area Selective Deposition (ASD) solutions include development of self-assembled monolayers (SAMs) and selective ALD/CVD growth.  Finally\, the talk will conclude with a description of the careers available in the semiconductor device manufacturing industry with an emphasis on research and development at Intel Corporation.
