Higgins, Simon - University of Liverpool

个人简介

My research interests are in synthetic chemistry applied to organic and molecular electronics. With colleagues in Liverpool, we study the electrical properties of individual molecules (using methods based on scanning tunneling microscopy) and how these properties vary with the structure of the molecules. We are also interested in the synthesis of semiconducting polymers for applications in organic electronic devices, but also more widely as (electro)catalyst supports.
