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.

Two new undergraduate students in our group  (03/01/14)

Victoria Cooley and Willa Cai are now our group members. Congratulations and good luck with their research projects!

Germanium-centered free radicals studied by muon spin spectroscopy – Can. 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! (11/04/13)

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)

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 − Organometallics (06/14/13)

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 (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 (03/27/13)

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.
