Research Interests

 Organometallic Polymer Chemistry:
Prof. Sheridan's research involves the design and synthesis of metal-containing polymers linked via π-conjugated organic/inorganic bridges. Specifically we have used hydrosilylation to prepare polymers containing silylene, phenylenevinylene or thienylenevinylene groups and ferrocene and troticene groups in the polymer backbone. The strategy is outlined in the schemes below and polymerization is achieved via hydrosilylation of dialkynes with metal-containing disilane monomers.


The polymers are characterized using NMR spectroscopy, Gel Permeation Chromatography and in some cases by MALDI-TOF Mass spectroscopy. The Silicon-29 NMR spectrum of the polymer 4a is shown below along with a typical MALDI-TOF spectrum for one of the ferrocene-containing polymers.
