Thank you!

A personal update on something else I’ve been working on… seven weeks earlier than expected!

Promotional graphic with the chemical structures of oxalyl dihydrazide and terephthalic dihydrazide.

Researchers studied the crystallisation of terephthalic dihydrazide (TeDi) and discovered that it unexpectedly forms two distinct crystal structures simultaneously when cooled in solution.

Love your mug!

@jacs.acspublications.org 💎

Haha, in the words of Shaggy “it wasn’t me!”. I blame @tobyjb.bsky.social 😅

That’s lovely!

Thank you!

This work would not have been possible without the collaboration with incredible scientists at Durham, York, and Southampton.

I am so pleased to see our work out in the world!

We also managed to isolate Form II with the use of a mimetic supramolecular gelator. The electron diffraction structure of the gelator reveals a similar herringbone structure to Form II, which allows the temptation and growth of Form II and the inhibition of Form I.

These discrepancies highlight and emphasise the tension between real crystals with defects, disorder, and twinning and idealised calculations, especially for polymorphs that lie within a small energy range.

Form I is stable for years at a time, while Form II disappears in solution within a day. We calculated the lattice energies of the polymorphs and generated the CSP landscape. All data suggested Form II was the most stable polymorph - the opposite of what we observe experimentally.

This work stemmed from my wonderful MChem’s preliminary results. She discovered the concomitant growth of two polymorphs (Form I and II) of a simple acylhydrazide. Further crystallisation studies of Form I revealed an accordion crystal morphology not seen before in organic systems.

When Reality Defies Prediction: Polymorphism, Twinning, and Accordion Crystals The ability to understand crystallization and predict the resulting solid form of a system is not always easily achieved, but it is critical, particularly in the field of materials science. Intriguing...

This is a special one for me. Getting any paper published in a peer-reviewed journal is amazing (especially as a corresponding author) but to be published in JACS is something else!

So pleased our review honouring Angelo Gavezzotti has been published! This work was driven by Aurora Cruz-Cabeza and her students, so I’m delighted to be a part of it.

Happy New Year!

Sorry sorry sorry Angelo*
I’m in hospital with flu if that helps my case for lack of attention to detail 😅

It is! There’s definitely lots to learn from it. Watch this space? 👀

Thanks, Dave. Very much appreciated. Have a great Christmas!

I wouldn't normally do science on Christmas Eve but the first independent paper of @amyvhall.bsky.social came out. We were honoured to be involved, providing our gelator. She converted into a hydrazone creating an amazing super-porous crystalline material, full of water.

We crystallised the bis(acylhydrazone) derivative of a well-known gelator, revealing impressive and large water channels running throughout, reminiscent of a HOF.

Thanks to the excellent Masters’ and PhD students, crystallographers, and collaborators (@professor-dave.bsky.social)

Merry Christmas!

Supramolecular Diversity in Bis(acylhydrazone) Crystals: Linker Effects, Polymorphism, and Gelator Assemblies A series of previously unknown bis(acylhydrazone)s with aliphatic (zero to four CH2 units) and aromatic (phenylene substituted) linkers was synthesized and structurally characterized. Aliphatic deriva...

Yesterday, I received an early Christmas present… my first solo corresponding author paper was published!

pubs.acs.org/doi/10.1021/...

We report the structures of bis(acylhydrazone) derivatives and how their behaviour changes with linker length and type – as well as three new polymorphs.

Haha, any time 🥁

Ba dum tss! 😂

Ooooooh 🤩

We have pioneered 3D-printing supramolecular gels by wet-spinning, using the patterns to grow cells for regenerative medicine (pubs.rsc.org/en/content/a...) or as soft conductors for nanoelectronics (onlinelibrary.wiley.com/doi/full/10....).
Here is a cool video!
