Chemical Panoptikum #1

Creating new substances, sometimes just for the sake of the creation act itself, is an undeniable part of chemists’ nature. Having flawless analytical data of a newly prepared sample always fills one with mystical joy and feeling of omnipotence. And some chemical creatures are so bizarre that the very fact of their isolation and characterization causes reverence of fellow chemists. So welcome to the chemical Panoptikum, a collection of all sorts of weird structures from the recent literature. Don’t be surprised to meet boron very often here, it’s a really weird element.

Radical Tricationic Rhomboid Tetraborane

Triple-charged radical, based on five-electron four-centered bond… Anything is possible in the boron world.

Antiaromatic Isophlorin

Turns out, if you substitute three out of four pyrrole rings in porphyrin, the macrocycle becomes antiaromatic.

Bored with BODIPY dyes?

How about Triple Boron-Cored Chromophores Bearing Discotic 5,11,17-Triazatrinaphthylene-Based Ligands?

Want something more challenging?

Try to squeeze two water molecules into C70 using molecular surgery.

And FYI

The Borosulfates K4[BS4O15(OH)], Ba[B2S3O13], and Gd2[B2S6O24] can be conveniently prepared from H[B(HSO4)4].

I did my PhD in medicinal chemistry/chemical biology of G protein-coupled receptors and then explored some chemical biology of non-coding RNA as a postdoc. Currently I'm working in a small biotech company in San-Francisco Bay area as a research chemist. I'm writing about science, which catches my attention in rss feed reader and some random thoughts or tutorials.
