Also out this week, part of Meabh's Honours research project investing what happens when you add methyl substituents to amidinium groups and try to make HOFs from them. Weird stuff is what happens. pubs.acs.org/doi/full/10....

Hydrogen-Bonded Networks from Poly(dimethylamidinium) Cations and Polycarboxylate Anions

Two ditopic and one tetratopic dialkylamidinium-containing compounds were synthesized and their ability to form hydrogen-bonded networks or frameworks with polycarboxylate anions was studied. A series...

Great to see this collaborative project led by @jona-foster.bsky.social reporting the first halogen-bonded nanosheets out: advanced.onlinelibrary.wiley.com/doi/10.1002/... Congrats to first author Prioti and the whole team.

Michael McGuirk and I wrote an tutorial review on supramolecular frameworks (hydrogen bonds, halogen bonds, chalcogen bonds etc) where we try to get everyone to agree on some common definitions for things. Might be a long shot! Hopefully useful for new students. pubs.rsc.org/en/content/a...

Defining, designing and determining the structure of supramolecular frameworks

Supramolecular frameworks, ordered porous networks assembled by noncovalent interactions, are a broad class of functional materials with emergent combinations of properties arising from the relatively...

We have a new paper out with Annie Colebatch: we metalate 6+ hydrazone cages to give M3-cage metallocages with coordinatively unsaturated metal ions. Et solubilising groups give expected 3-fold symmetric metallocages. OMe or OPr give funky low-symmetry cages tinyurl.com/4ehppaex.

Low Symmetry Cage Complexes Formed by Metalation of Symmetric Hexa‐Cationic Organic Cages

Threefold symmetric hexa-cationic hydrazone cages coordinate a range of transition metal ions upon deprotonation. When the cage contains ethyl solubilising groups the expected threefold symmetric cag...

Very good thread on the silliness of impact factors.

Valentin Rodionov@arbitraryeffect.bsky.social · 12mo ago

This is an excellent illustration of how useless the "Impact Factor" metric is. The most influential multidisciplinary chem journals are JACS and Angewandte. They did not make the list. In this short ad hoc 🧵 I will analyze in real time what made the list and why. I have a bad feeling about this.

2024 journal impact factors are out, and I had a bit of a play around comparing the numbers with 2019 IFs. Bit of a thread to follow, but general trend seems to be most journal IFs are trending downward but JACS/Angew and big “less-selective” journals buck the trend.

We have a 3-year postdoc position available, starting in October, to work on molecular capsules for catalysis. Click on the link below to apply! 👇 Happy to have informal chats about the post - send me an email. Application deadline 6 July. edzz.fa.em3.oraclecloud.com/hcmUI/Candid... #chemsky

Does anyone tech-savvy know if there's a browser extension or something that get journals to just show me the normal pdf rather than their annoying epdfs? Manually deleting the e from epdf in the web address and reloading is getting tedious. #chemsky

Who among us hasn't wanted to prepare a "mental-organic framework?" #chemsky

Bit belated (thanks COVID), but thanks to everyone who came to Supramol25 in Canberra last week. Some great plenaries and prize talks, and most impressively of the ~ 30 talks over 2 days, not a single one was in 4:3 format! I think this might be a career highlight.

1 pm Saturday: invitation to review a revision of a manuscript I've previously reviewed 6 pm Sunday: "I recently invited you to review this manuscript and have yet to receive your response" I get that journals want things signed off before Christmas, but this seems a bit much!

We report porous halogen bonded frameworks, assembled using NaCl ion pair templation. Not stable to evacuation but stable to solvent exchange and iodine vapour. Congrats to first/corresponding author Jordan who designed the system and visiting Edinburgh MChem student Callum who first made them.

Porous Halogen‐Bonded Frameworks Assembled through Hetero‐polytopic Ion Pair Templation

A tetratopic halogen-bond donor with a discrete cation binding site was designed and synthesised. When crystallised with NaCl, a 3D framework is formed where the charge-balancing cation is sequestere...

New paper: We prepare robust organic cages in two steps and on large scales (up to 14 g). These can bind sulfate selectively in water. First paper in collaboration with Annie Colebatch and her group. pubs.acs.org/doi/full/10....

Expedient Decagram-Scale Synthesis of Robust Organic Cages That Bind Sulfate Strongly and Selectively in Water

Selective anion recognition remains a key challenge in supramolecular chemistry: only a very small number of systems that can function in water are known, and these nearly always preferentially bind h...

Is it OK to post papers on Bluesky? If so, end-of-year paper collaboration with Lauren Macreadie, pubs.rsc.org/en/content/a... You can put cubane and bicyclopentane in hydrogen bonded frameworks, and they still absorb (a lot of) water vapour.

Hydrogen-bonded frameworks containing aliphatic 3D linkers show high-capacity water vapour sorption

Hydrogen-bonded frameworks were prepared from a tetra-amidinium component and three-dimensional cubane and bicyclopentane dicarboxylate linkers. Despite the incorporation of aliphatic components, the ...

Great to be back in Aotearoa-New Zealand where the intercity coach I'm on also doubles as the medical courier to get blood samples to the hospital in the "big" city
