The versatile world of cumulene chemistry Despite a history spanning over a century, cumulenes are often relegated to the realm of perceived curiosities rather than practical synthetic intermediates as a result of their high intrinsic reactiv...

Finally finished. Wanna know how cumulenes react? Check out the review from Kate and Abhishek!!!

And a great collaboration with @gawelpchem.bsky.social

We are hiring, two fully funded MSc/PhD positions available.

Allenes as Stimuli-Responsive Chromophores for Visible to Near-Infrared Optical Modulation Despite their rigid, orthogonal π-systems and synthetic modularity, allenes remain underexplored in functional material design. Here, we report that tetraaryl-substituted allenes undergo clean and rev...

Super stoked about our second JACS! We establish allenes as reversible halochromes with dramatic optical property switching. This work could not have been this successful without the amazing support from @minjungson.bsky.social at BU and the Ding Lab at WFU. Check it out

Substantial Magnetic Fields Arising from Ballistic Ring Currents in Single-Molecule Junctions When a small electric bias is applied to a single-molecule junction, current will flow through the molecule via a tunneling mechanism. In molecules with a cyclic or helical structure there may be circ...

It has been underway for several years. Finally, our proof-of-concept study on the magnitude of magnetic fields arising from coherent electron transport in single-molecule junctions is published. This is an initial step towards designing a single-molecule electromagnet. pubs.acs.org/doi/10.1021/...

High energy density dihydroazaborinine dyads and triad for molecular solar thermal energy storage The reversible photoisomerization of 1,2-dihydro-1,2-azaborinines (BN benzenes) to their Dewar isomers (2-aza-3-borabicyclo[2.2.0]hex-5-enes) provides a promising platform for molecular solar thermal ...

Verdazyl-Based Radicals for High-Field Dynamic Nuclear Polarization NMR High-field dynamic nuclear polarization nuclear magnetic resonance (DNP NMR) spectroscopy transfers polarization from unpaired electrons in polarizing agents to nuclei of interest to boost NMR sensitivity. Verdazyl biradicals are a promising choice as polarizing agents because they have been found to generate narrower electron paramagnetic resonance (EPR) signals compared to nitroxide biradicals; an advantageous characteristic for high-field DNP when operating above 400 MHz/263 GHz. The use of verdazyl radicals as DNP polarizing agents has been very limited to date, yet, recent numerical simulations have predicted that verdazyl-nitroxide hybrid biradicals could be more effective polarizing agents than nitroxide-nitroxide biradicals. Herein, the syntheses of a series of verdazyl mono- and biradicals, as well as verdazyl-nitroxide biradicals are described. These radicals were examined in high-field DNP NMR experiments (600 MHz/395 GHz), by measuring 1H signal enhancements directly and through 13C{1H} cross-polarization experiments. X-band EPR, 1H DNP field profiles, and experiments to determine the nuclear build-up times were performed for verdazyl-nitroxide biradicals VerTEMPol and VerTEKol. These hybrid biradicals provide enhancements of up to 100-fold increased signal intensities (i.e., representing >104-fold time savings), approximately four times higher than that of the nitroxide biradical TEKPol, a commonly used polarizing agent in the field.

Congrats to Jakob (first author JACS as an undergrad!!), Zack (the proud mentor and force behind the project), and all the great collaborations with the Brown and Michaelis Groups!
