It was a great pleasure to welcome Prof. Shuhei Furukawa (@furukawas.bsky.social) from Kyoto University for a fascinating talk on “Van der Waals Porous Solids.” He shared inspiring insights into metal-organic polyhedra and engaged in lively discussions with our group!
Shun @shuntokuda.bsky.social , Perry, and Bibhuti @bbrath.bsky.social successfully survived the 24-hour experiments at the BESSY II 14.1 single-crystal beamline 💫💠 They are very excited about the many new structures upcoming!
✅This week’s Chemical Science Pick of the Week is “Phase-Dependent Responsiveness in Soft Porous Crystals Assembled from Flexible Metal-Organic Cages” by Professor Shuhei Furukawa et al. from Kyoto University. You can read for free here: doi.org/10.1039/d6sc...
I did not expected that this photo goes for social media… 😅 We look somehow much more professional than we actually are 😂

When your single crystal was not happy with the synchrotron radiation:
Let me share my 2 min of excitement and following 1 day of regret.
Here is the t-slice movie for the low temperature structure of CeHOTP
We aim for high-level research, so we decided to put ourselves at the highest altitude in Germany - the Zugspitze! 🏔️❄️☃️ This year's group retreat was fully surrounded by snow, but the confinement effect in the mountain successfully induced our red-hot, strong bonds once again 🤝🤝
End of my short trip in Stockholm for the Nobel week. It was a great opportunity to listen to the three legends’ behind stories in person. Fingers crossed that I have another chance to come back here.
We found MOPs can be “packed” into fibrous structures instead of crystals by the careful solvent control! Check out Ayana’s first manuscript, now on the ChemRxiv!!! 👀
Shuhei Furukawa@furukawas.bsky.social · 11mo agoArraying MOPs into one-dimensional structures via van der Waals interactions creates new porous aerogels. Three years of Ayana's work is now posted on @chemrxiv.org!! chemrxiv.org/engage/chemr...
We designed soft porous crystals based on flexible MOCs!! MircoED enables us to characterize two distinct activated phases of MOCs: one is flexible, and the other is rigid. Nice teamwork with Donglin, Javi @cabrelles497.bsky.social, and Jack!! Posted on @chemrxiv.org. chemrxiv.org/engage/chemr...
Phase-Dependent Responsiveness in Soft Porous Crystals Assembled from Flexible Metal–Organic Cages
Soft porous crystals (SPCs) based on flexible metal–organic cages (MOCs) remain elusive due to challenges in preserving both dynamic behavior and crystallinity after desolvation. Here, we report an SP...

My tutorial review on single crystal diffraction analysis is now online @crystengcomm.rsc.org! Students, supervisors, and reviewers: Please consider this thought-provoking read to discover many facets of the crystallographic practice that are often overlooked or misunderstood 💎 #crystallography
Useful practices in single crystal diffraction analysis of reticular structures
Single crystal diffraction analysis remains the gold standard for the three-dimensional atomic structure characterization of framework materials such as metal–organic frameworks, covalent organic fram...

Celebrated the day 1 of my new hobby with this coolest framework
AI can now generate fake microscopy images that are nearly impossible to detect. A serious threat to scientific integrity—and we’re not prepared for it. Commentary in @natnano.nature.com #nanotechnology
Really happy to see this team effort out in Angew. Chem., where we used 3D electron diffraction to observe a metal-organic polyhedron-to-polymer transition, and observe the activated phase. Big thanks to @leverhulme.ac.uk for supporting our work on this. onlinelibrary.wiley.com/doi/10.1002/...
A Metal‐Organic Polyhedron‐to‐Coordination Polymer Transition Revealed by 3D Electron Diffraction
Here, we show that 3D electron diffraction (3D ED) is an effective technique to observe structural transformations in porous metal-organic polyhedra (MOPs), as well as for obtaining the structure of ....

I fully enjoyed the intense week in the 6th International School on Aperiodic Crystals at MPI-CPfS in Dresden! A chunk of minerals for my poster prize is a real treat for the painful learning curve I had in the 6D space of quasicrystals. Huge thanks to the organizers for opening this amazing school!
Come join our team! We have a PhD position available on noncovalent interactions in COFs. The position is part of the BEAM graduate school. (Details in the alt text)
Check out this Jiyeon’s beautiful work on the realization of quasiperiodicity with MOFs! 🎉🥳 Beautiful structure does not always have to come with periodicity, even with MOFs!
Jiyeon Kim@jiyeonkim.bsky.social · last yr.Just out in Nature Communications! @natcomms.nature.com We dive into the quasiperiodicity of moiré 2D MOFs😉🔬 Grateful to Prof. W.Choe and our team, and to collaborators Prof. S.S.

My first beamtime at BESSY II MX14 were fantastic!! 💫 Huge thanks to the beamline scientists for the warm supports and of course to Stefano @stecanossa.bsky.social for the diffractive discussions as always!
Wrapped up 24 intense hours at BESSY II, lots of data, and a truly valuable experience. Huge thanks to @stecanossa.bsky.social and @shuntokuda.bsky.social for the help, and to @simonkrause.bsky.social for all his support. Looking forward to data analysis 😊
