This diffraction pattern is from one of the most exciting structures I got so far. Collected with 'naked' beam at synchrotron, poor res, but solves. The problem is that some atoms in the side-chain are 'missing' and can't really be located with this data quality and possibly a disorder... 😭😭😭

Why would you draw a whole molecule 😊

Wojtek Stawski @stawskiwojtek.bsky.social · 1d

Super happy that I could contribute to this excellent paper! The holy grail of oligo-porphyrin chemistry was finally made 😍

Lots of great chemsky content in @science.org this week, including a remarkable porphyrin nanobelt from the Saywell and Anderson groups 🧪

Goodbye, Diamond! See you remotely next time! 💎

The gods of crystallography have been relatively good for us today 💎

Very nice work. It’s probably my second favourite tutorial right after Amber’s paper! www.tandfonline.com/doi/full/10....

Chemical Crystallography: when are ‘ bad data’ ‘good data’?

There is an increasing trend to reduce diffraction data collection to a set of numbers and the crystallography to a set of criteria. Many of these criteria have been passed on through generations o...

First-ever preparation of shipping of crystals to @diamondlightsource.bsky.social in our group @besserchemistry.bsky.social is finished! We’ll find out how good my technique was in about two weeks 😄

Wojtek Stawski @stawskiwojtek.bsky.social · Aug 28

Successful collection of a dataset at DESY. Now have one macrocycle crystallised as three different solvatomorphs with different packing!

It’s the second time when I was able to sign it. In three other cases the journals did not give that possibility.

Wojtek Stawski @stawskiwojtek.bsky.social · Aug 25

Feels so nice when you get a paper to review, you suggest some revisions and then authors introduce them and it all looks so much better! #HappyReviewer P.S. Also decided to reveal my identity in the report in the end. I think it’s fair.

The best solution of the problem - stop calling it a problem, just don’t fill it 😅

Checking whether anyone did an experiment I need while writing a paper and finally found it. Reference to a spectrum I was searching for: „Author X, Author Y, PRIVATE COMMUNICATION”. 😅😅😅 How was it even allowed?!

I noticed that recently these kind of ciecular diagrams got very popular as TOCs; however, not sure if it’s just me but I find them completely non-readable and when I see them I immediately skip the article 😅😅😅 Random example attached

Wojtek Stawski @stawskiwojtek.bsky.social · Jul 24

It’s my new crystal baby😊

Wojtek Stawski @stawskiwojtek.bsky.social · Jul 14

Well, a crystal structure of one the cyclocarbons alone would probably make quite a high-impact paper 😅

Weekend in Albania 🇦🇱

Wojtek Stawski @stawskiwojtek.bsky.social · Jun 25

Yeah, maybe it’s so well separated that it doesn’t change much…. Here’s a look at the Ewald sphere. It says that the two domauns are related by 177deg rotation so maybe more of a split crystal rather than a proper twin? No idea, don’t have much experience with twinning cases

Wojtek Stawski @stawskiwojtek.bsky.social · Jun 25

Struggling with a terrible twin refinement. Everything looks OK during processing and when adding data from second component to the refinement it just doesn’t change almost anything in the R values… 😓 And the dataset is quite good, with nicely separated reflections! #crystallography

Picked a big boy today. Not bad for something with molecular mass of 2500 😌

Action: retraction 😋

Wojtek Stawski @stawskiwojtek.bsky.social · Jun 10

Large number of stuff I’m crystallizing now works only in tetrachloroethane. Had some terrible disorder with it. After two days of playing with it decided to push the SQUEEZE button ☠️

7h HSQC on a compound that gives signals with height half of the solvent’s 13C satellites and it looks good! 😌

Poor water 😢
