The humble pumpkin has found itself increasingly popular with artists wishing to outdo each other with their carving skills, but pumpkins have also found a home amongst equally competitive chemists shaping their constructions.
If you’re beginning to think I’ve been hit with a confusion spell then never fear, I’m simply referring to the modest cucurbituril. This molecule gets its name from the term for the pumpkin family. There’s apparently a resemblance between the ribs of the pumpkin and the bonds of the macromolecule. But this similarity is nowhere better shown than in the Halloween themed cover of the latest edition of Chemical Science.
This cover brings us into the darkness of a pumpkin-scientist’s den, light spilling through carved features illuminating the creations within. Looming large on the desk is a ghastly pumpkin, smiling whilst xenon bats flitter in and out of its gaping mouth. The desk is also littered with smaller cucurbiturils and a structure half way through its transmogrification into a fully-fledged pumpkin-xenon-bat-exchanger-thing. On the left side stands an old cage and a bat confined within. A dusty spider’s web blocks the exit, which is also being guarded nearby by acryptophaneunwilling to release its hostage. (more…)
