About the Organosilicon Research Center
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 Center.
With corporate and government support, the Center's mission is to carry out
fundamental research which already have applications in the organosilicon industry.

Stability of organosilicon
electrolytes for lithium-ion batteries in Journal of Power Sources
The study 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 solvents.
14th International Conference on the
Coordination and Organometallic Chemistry of Ge, Sn and Pb
in Nova Scotia, Canada (07/14/13)
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
Silicon for OLED fabrication and bioimaging (04/26/13)
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
