Chemical Selectivity in Surface Deposition Reactions

Prof. Zhe She
Department of Chemistry
Queen’s University

Modification of material surfaces can tune the properties and functionalities of the materials. Formation of self-assembled monolayers (SAMs) has been studied extensively in the past 35 years. N-heterocyclic Carbenes (NHC) SAMs have emerged into the area in the past decade as an alternative option to popular thiols. 1,2 NHC SAMs could potentially be very useful for sensing, electronics and corrosion protections. We have been studying these molecules towards developing applications in electrochemical biosensing and microfabrications.3,4

In this presentation, I will share some of the stories from the journey.
