📣 Call for postdocs 📣 Our newly established team is up and running and ready to expand: do you enjoy supramolecular chemistry and/or catalysis? Check out our ERC postdoc vacancy Dipartimento di Scienze Chimiche - UniPD University of Padua Research: euraxess.ec.europa.eu/jobs/249683 #chempostdoc Postdoc Predoc Opportunities The Postdoctoral


It is not every day that one will have the honor and opportunity to invite both his/her PhD Sorensen Family and postdoc Fraser Stoddart advisors to dinner together. Thanks so much for everything. A day and a night to remember😃



My research group joined me in hosting Erik Sorensen (Sorensen Family), Aspen Chen (Aspen Chen), Jay Siegel, Kim Baldridge, Ken Leung & Chris Lee to a Korean BBQ dinner. It was a memorable evening talking about the contributions of chemists, past, present and future, to science.


Building on reticular chemistry principles, we’ve expanded our covalent organic pillars into a larger iCOPs family. These discrete nanotubular structures act as deep cavitands, ideal for hosting long alkyl guests. Check out the extensive X-ray crystal structures at J. Am. Chem. Soc.!


Point-catenation unlocks hydrogen-bonded organic frameworks for H2 storage. Check out our article in Nature Chemistry featuring 7-fold catenated supramolecular crystals with high BET areas and record-high volumetric H2 storage capacities.

A great pleasure and honor meeting with Professor Coskun Ali Coskun and Professor Banerjee Rahul Banerjee! Thanks SK Seungkyu Lee for organizing.



Cracking the challenge of synthetic lectins! Our latest in Chemical Science introduces a tetralactam macrocycle that binds glucose in water with over 5x the strength of natural lectin ConA. Bonus: a stunning crystal structure! bit.ly/3Cm9KQZ


Electrostatic interactions turn out to be a dominant factor in determining the pre-organization of carboxylate guests in CD-MOFs. This observation could open up many opportunities for engineering chemical reactions in confined spaces. Dengke Shen 沈登科 Fraser Stoddart HKU Chemistry

The fundamental message from this research is that it’s possible when substrates are bound in nano-sized receptors for one binding source to become dominant over all the others, i.e., many a mickle makes a muckle doesn’t always have to rule the roost. Northwestern Chemistry HKU Chemistry



Thrilled to share our Nature Synthesis paper on a compact catenane with tuneable chirality! Honored to have worked with Fraser (Fraser Stoddart), whose inspiration and support guide us and live on. doi.org/10.1038/s44160…


Thrilled to share our recent progress in synthesizing enantiopure conjugated nanotubes using axially chiral BINOL-based building blocks! These structures exhibit strong CPL activity and remarkable hosting capabilities. CCS Chemistry

Our latest J. Am. Chem. Soc. paper is out! A 2.6 nm metal–organic pillar tubular host that shows anion-dependent chiral self-sorting and selectively recognizes long-chain “bad” saturated fatty acids over “healthy” polyunsaturated ones like DHA. 🔗 pubs.acs.org/doi/abs/10.102…
