"Synthetic Discoveries from Polycyclic Natural Products"


"In  the  pursuit  of  the  synthesis  of  biologically  active  natural  products (compounds  originally  isolated  from  natural  sources),  powerful  reactions  using organic or acid catalysts (i.e., not transition metal based) have been developed. The   new   chemical   transformations   thus   made   available,   along   with   the extraordinary  chemical  compatibility  the  new  catalysts  provide,  have  enabled access to a variety of new target motifs for synthesis. Increased understanding of the catalytic mechanism and of the role of each reaction component have also led  to  additional  applications  of  the  mechanistic  paradigm  to  new  chemical"
"transformations that utilize other classes of catalysts."

Organic Chemistry Seminar: Dr. Bekka Klausen, John Hopkins

Mon, 2018-10-01 12:00 - 13:00
Speaker: 

Dr. Bekka Klausen

Title:
Unconventional Building Blocks for Functional Polymeric Materials
Abstract:
The Klausen group designs and synthesizes unconventional molecular building blocks
for the construction of diverse functional polymeric architectures. Motivated by the conviction
that the synthesis of new materials drives the discovery of new applications, this talk will
describe the synthesis and polymerization of novel hybrid inorganic-organic monomers. The
materials we prepare are expected to find application in energy science as earth abundant
quantum materials or as plastics with finely controlled physical properties.
The semiconductor silicon has revolutionized life in the last century, from the
development of computer chips to the discovery of solar cells that make telecommunication
satellites possible. The frontier for silicon research and development is at the nanoscale. The
incredible potential of nanoscale silicon arises from the attractive properties it shares with bulk
silicon, such as earth abundance and low precursor toxicity, and the distinctive optical and
electronic properties emerging at small sizes. This talk describes the design and synthesis of
new molecular forms of silicon, as well as the characterization of materials properties and the
fabrication of electronic devices based on molecular silicon.
BN 2-Vinylnaphthalene (BN2VN) is a solution to a long-standing challenge in polymer
chemistry, the copolymerization of nonpolar and polar monomers. Though the incorporation of
polar functionality into nonpolar polymers is an essential strategy for modulating physical
properties, challenges in their direct copolymerization include phase separation, significant
differences in reactivity, and the limited compatibility of polar functional groups with
polymerization catalysts. We show that BN2VN retains the reactivity of styrene, while postpolymerization
modification of the C-B bond provides hydroxyl-functionalized polymers, or
styrene-vinyl alcohol (SVA) copolymers.

Organic Chemistry Seminar: Dr. Richard Hark, Yale

Speaker: 

Dr. Richard Hark

"Preparation, Passion and Serendipity: Reflections on an Unfinished, Non-Traditional Career in Chemistry"

- "What do you want to be when you grow up?” is a question that is not directed solely to young children. Undergraduate and graduate students may wonder at times what they will do with their chemistry degree after graduation. In this seminar, the speaker will publicly confess that he is still trying to find the answers, even after a twenty-five-year career as a chemistry professor at liberal arts colleges. Though each person has to figure this out for themselves, the talk will provide some useful observations and general advice as Dr. Hark shares examples of how his training as a synthetic organic chemist at Penn provided the foundation on which to build an interesting and fulfilling, albeit somewhat non-traditional career.  Interspersed in the presentation will be examples of his broad research interests that include synthetic and analytical work in the fields of chemistry, forensics, geochemistry and conservation science.
