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!

Our recently published paper (ACS Omega 2016, 1(6), 1336-1342) on sultam-based deep-blue organic emitters has seen almost 1000 downloads in under three months, making it the most viewed article of Volume 1, Issue 6 (Dec 2016).  Link to article

New faces for the new year

At the beginning of 2017, the Chan Research Group welcomed Dr. Prabhat Gautam (postdoctoral fellow) from India and Ms. Janire Matas (visiting researcher) from Spain. It has been two weeks now, and the both of them are adjusting very nicely. Prabhat is working on donor-acceptor π-conjugated systems, and Janire is researching redox-active polymers for battery applications. [Link]

Chan Research Group - 2016 in Review

2016 was an eventful year for the Chan Research Group. We had two graduate students and a visiting researcher join our team, major renovations done, instruments purchased, and our first paper published. Here's looking back at our first year of operation:

Feb 2016:   Dr. Chan was awarded an NSERC Discovery Grant.
Mar 2016:   Renovations to our D'Iorio 327 and 320 labs began.
Apr 2016:   Thomas Brossier, visiting MSc student from Paris, arrived in Ottawa.
Jun 2016:   Guoxian and Craig joined us as grad students.
Aug 2016:   Lab renovations complete. The Chan Group moved in.
Dec 2016:   Published our 1st paper on sulfonamide emitters in ACS Omega [link].

Sulfonamides for Organic Electronics - Deep-Blue Emitter

My team recently reported a sulfonamide-based blue-emitting organic fluorophore that exhibits crystallization-induced emission enhancement.[1] Sulfonamides remain highly underutilized as functional groups in organic electronics and should be further explored as versatile molecular motifs for engineering structure-property-function relationships.

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.
