No, sorry, you are right

I see a smaller unit cell 😏

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 🤝🤝

When a single word is more than just that.

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.

Are you coming to the MOF commemorable symposium at the Museum? I’m also flying there today 😀

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!!! 👀

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...

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.

Day5 is for another flexible family.

The metal-oxo 1D chain was a little bit tricky to design in this model.

Day4: Let’s celebrate the Nobel prize with this legendary one

Spot one substitutional defect

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...

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

You can actually see expansion in the a-b plane when pushed along c axis
I’m still hesitating to make the rigid counterpart MIL101

On day3 I welcomed a flexible family member

Day2 is this open metal site guy

It is easy to synthesize, but was quite tricky to assemble with papers

Good idea! Let’s see how German beer accelerates my creativity 🍺

There are too many in the waiting list, but I would be happy to hear recommendations for the next 🙂

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.

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 ....

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.

Thanks! It was really an exciting experience to be among this community as a chemist

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!

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!

Isoreticular moiré metal-organic frameworks with quasiperiodicity - Nature Communications Twisted bilayer metal-organic frameworks produce dodecagonal quasiperiodic moiré patterns with tunable length scales. Here the authors show that isoreticular ligand design enables control over aperiod...

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. Park and Prof. J.Kim for their contributions.

Thursday on the way back from experiments at BESSY II. My brain was totally living in a reciprocal space and this pattern smoothly jumped into my eyes ;)

We are also pleased to guide @esengulciftci.bsky.social to our reciprocal curiosity space! Hope we can extract something interesting from your datasets🤞

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!

Sure! I actually did not realize there is a stacking fault when I took the picture, but now I love it more ;)
