It’s my first teacher’s day since joining Gachon University this year! My students surprised me with a cake — they really made my day.

Low-Temperature Direct Arylation Polymerization for the Sustainable Synthesis of a Library of Low-Defect Donor–Acceptor Conjugated Polymers via Pd/Ag Dual-Catalysis Donor–acceptor alternating conjugated polymers (D–A CPs) are one of the best materials for high-performance organic electronic devices, owing to their low bandgap and high charge carrier mobility. How...

New paper out in @jacs.acspublications.org !
In collab with Prof. Byoung Hoon Lee's group, we report a versatile & sustainable Pd/Ag dual-catalytic DArP at low temperatures, yielding low-defect D-A CPs. Big congrats to Hwangseok Kim, @gimongkim, Junmo Park, and teams!

I’ve wrapped up my time at the UMich, feeling deeply grateful. Huge thanks to my labmates for their support, inspiration, and friendship. I was especially touched by Nate’s handmade ceramic gift. I truly appreciate all the connections I made here and look forward to the next chapter!

A Holistic Data-Driven Approach to Synthesis Predictions of Colloidal Nanocrystal Shapes The ability to precisely design colloidal nanocrystals (NCs) has far-reaching implications in optoelectronics, catalysis, biomedicine, and beyond. Achieving such control is generally based on a trial-...

Exciting collaboration with LNCE (EPFL)!

We discovered a previously unreported copper nanocrystal shape by introducing a surface energy scale in our Bayesian optimization loop (-> Rhombic Dodecahedron)! Congrats to BOjana and LUDO!

Air and Thermally Stable Cyclic (Alkyl)(amino)carbene Ruthenium Complexes for Efficient Ring Expansion Metathesis Polymerization Ring expansion metathesis polymerization (REMP) has emerged as a potent strategy for obtaining cyclic polymers over the past two decades. The scope of monomers, however, remains limited due to the poo...

Excited to share our work (@eunsunglee.bsky.social) in collaboration with Prof. Tae-Lim Choi's group! Air-stable ruthenium catalysts with tethered CAAC ligands for REMP. A heartfelt thank you to the reviewers and editor for their invaluable advice! doi.org/10.1021/jacs...

For all those providing reviews of scientific papers–firstly, thank you. We would not have a useful scientific literature without you. Secondly, please keep in mind that your reviews are read not only by the PIs but also students. There is no place for anger or impolite language in a review.... 1/

Site-Selective Copper(I)-Catalyzed Hydrogenation of Amides We present a bifunctional catalyst consisting of a copper(I)/N-heterocyclic carbene and an organocatalytic guanidine moiety that enables, for the first time, a copper(I)-catalyzed reduction of amides ...

Colleagues, Students, Postdocs, Collaborators and Friends of Sir Fraser Stoddart: I am writing with the sad news that Fraser passed away suddenly on 31 Dec (Australia time) while on holiday with family. No details yet on any services. He is irreplaceable.

A fun little journey through the 100 year history of the Cp+ cation.

A Dewar style upright tank for liquid nitrogen lies on its side, venting nitrogen cryogen onto a pebbled sidewalk near a bike lock station and brick wall.

Let's see how many scientists cringe when looking at this image: a liquid nitrogen Dewar that has been modified with welded-on wheels, which hit the uneven pavement outside the Welch Chemistry building at the University of Texas and promptly tipped over, rupturing the valve & spilling cryogen.

A metal-free strategy to construct fluoroalkyl–olefin linkages using fluoroalkanes We present a metal-free strategy to access fluoroalkyl–olefin linkages from fluoroalkane precursors and vinyl-pinacol boronic ester (BPin) reagents. This reaction sequence is templated by the boron re...

Borirene - Wikipedia

Teaching update: The last few main-group graduate courses I've taught have produced Wikipedia articles, that are internally peer reviewed, to make main-group content more accessible to the public. One of this year's first to be posted is on borirene: en.wikipedia.org/wiki/Borirene

Great!! Add me please~
