102nd Canadian Chemistry Conference & Exhibition, Québec City

It was a nice week of chemistry at the CCCE 2019 in Québec City. Thankful to Thomas Baumgartner and Alex Adronov for inviting me as a guest speaker for the Innovative Concepts in Organic Materials Symposium. Some photos of the host city:

Winning the New Frontiers in Research Fund (NFRF)

I have been awarded the inaugural NFRF, which carries research funding of > $228K CAD. Very grateful to the Tri-Agency (SSHRC, NSERC, CIHR) for this generous grant. Synopsis of my research proposal:

Prof. Julian Chan, Department of Chemistry, Faculty of Science

"Probing Novel Molecular Designs for Organic Excitonic Superconductors"

The discovery of new materials that conduct electricity without resistance — and thus without power loss — would revolutionize the way we transmit, store and use energy. Dr. Julian Chan and his team are exploring novel chemistries to create exotic organic molecular structures that exhibit superconductivity at high temperatures.

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 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.

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.
