Polymer electrets for organic nonvolatile memory devices

Our joint review article with Prof. Cheng-Liang Liu (National Taiwan University) on polymer electrets is now out in Materials Today Chemistry. Polymer electrets are organic materials that are capable of trapping electronic charge; this property is key to their application in information storage. Find out how they work and learn about their chemistry!

Sulfonamides in Organic Electronics - Blue-Emitting Helicene

Compared to red and green emitters, organic luminogens that emit standard- and deep-blue light remain challenging to design. Our recently published π-conjugated helicene is a deep-blue fluorophore in solution and the solid-state, with PL efficiency more than twice enhanced in the latter. This new sulfonamide / sultam-based motif introduces a brand new weapon to the arsenal of blue-emitting building blocks (e.g. triphenylethene, triarylamine-based systems). While common in pharmaceutical chemistry, sulfonamides are rare guests in organic electronics and thus represent a tantalizing possibility to explore.

Chan Research Group - University of Ottawa (Chemistry)

I am an Assistant Professor of Organic Chemistry in the Department of Chemistry at the University of Ottawa. I am also the principal investigator of a research group that is working to develop novel functional organic materials. Specifically, we are designing and synthesizing π-conjugated organic molecules and polymers with unique optoelectronic, magnetic, and/or biological properties.
