About the Organosilicon Research
Under the leadership of Professor Robert West,
the organosilicon research group at Wisconsin
has been a major center for studies of silicon chemistry for more than
forty years. Eighty students have earned Ph.D. degrees in this group, and
more than 130 postdoctoral fellows from 14 different countries have done
research in the group. Major discoveries include soluble polysilane
polymers and their semiconductivity (1980), the silicon-silicon double bond
(1981), stable divalent silicon compounds (1994), a new model for polymer
conformations (2000), and muon spin resonance spectroscopy of silicon,
germanium and phosphorus compounds (2009-2013).
In 1999 the group became the Organosilicon Research
corporate and government support, the Center's mission is to carry out
fundamental research which already have applications in the organosilicon

Germanium-centered free radicals studied by muon spin spectroscopy
J. Chem. (12/20/13)
Nine different divalent
germanium compounds (germylenes) were studied by muon spin spectroscopy.
The results of this investigation are summarized in Can. J. Chem.
Sisi won a Trewartha senior thesis grant!
Our undergraduate student Sisi He won a prestigious Trewartha
grant. Congratulations to Sisi for
her successful proposal!
Stability of organosilicon electrolytes for lithium-ion batteries in
Journal of Power Sources (08/25/13)
of thermal and electrochemical stability of organosilicon electrolytes for
the most popular energy portable storage systems, lithium-ion batteries,
showed that they are safer alternatives to more commonly used carbonate
14th International Conference on the Coordination and
Organometallic Chemistry of Ge, Sn and Pb in Nova
Prof. West presented the recent results on muon spin resonance
spectroscopy of stable germylenes.
Special issue of Journal of
Organometallic Chemistry – (06/31/13)
JOMC celebrates the 50th anniversary of organometallic
chemistry. Alex’s paper on the
interesting transformations of spirogermabifluorene upon reduction with
alkali metals has been accepted for the publication in this special issue.
Silicon in a Negatively Charged Shell −
Alex’s research about the charged polycyclic systems
containing a central Si-atom has been just published in Organometallics. This
fundamental work describes the conjugation of two aromatic systems together
over the sp3-hybridized silicon atom The theoretical part for
this work was done by Dr. Andrey Rogachev (Cornell). Dr. Ilia Guzei
(UW-Madison) carried out X-ray diffraction studies.
Organosilicon Community will meet in
Lubbock, TX − 45th Silicon Symposium (05/21/13)
The foreword for the Symposium was written by Robert West, who also
gave an invited lecture about the organosilicon electrolytes for lithium
ion batteries. Alexander
Zabula gave an oral talk about the anions of spirosilabifluorene.
Highly Fluorescent Diquinaldinatoalumino
Silole Derivatives in Chem. Eur. J.– (05/16/13)
Erika Pusztai’s paper
on the synthesis and photophysical properties of silicon compounds has been
published in Chem. Eur.
J. Blending the strong emitter, diquinaldinato aluminum, and the good
electron transporter, tetraphenyl silole, resulted in highly fluorescent
compounds that are promising candidates for light-emitting devices without
the need of dopants.
Silicon for OLED fabrication and bioimaging
Synthesis and photophysical properties of asymmetric substituted
silafluorenes are published in Organometallics.
The non-toxicity of silafluorenes in cell cultures coupled with interesting
fluorescence properties makes these compounds very promising for the
application in bioimaging.
What's new in Silicon Chemistry –
The nature of Si−O bond in JACS
The most abundant chemical bond on the earth, Si−O, was
studied by computational methods in collaboration with Prof. Frank
Weinhold. The corresponding research is summarized in the JACS paper.
Alexander Zabula has
joined to our group (10/01/12)
Alex came to Madison
from Albany, NY. His primary research focus will be
centered on the low-valent derivatives of main group elements.
