I'm very honored to receive UNC's Postdoctoral Award for Research Excellence. I've had a wonderful time these last few years exploring the world of PCET kinetics and mechanisms. Here's to hoping for many more as an independent P.I. next Fall!.
🎉 Congratulations to the College's recipients of the Postdoctoral Awards for Research Excellence. Kaneesha R. Johnson, political science, and Matthew Kessinger, @uncchemistry, received the honor for outstanding research promise. @kessm05 @UNCPostdoc

208: This was an interesting article. I've always been curious whether the metal or the porphyrin is the formally reduced species that operates during these catalytic reactions. This report suggests it's the porphyrin!.
pubs.acs.org
Iron porphyrins can act as potent electrocatalysts for CO2 functionalization. The catalytically active species has been proposed to be a formal Fe(0) porphyrin complex, [Fe(TPP)]2– (TPP = tetraphen...

D207: Eva made today's paper easy to find! @enicholschem, could the deviation from the trend in del_S by the -OMe derivative be explained by a hydrogen bond between the -OMe oxygen and the acid that leads to a more ordered transition state?.
@kessm05 Hi Matt, we've measured some temperature-dependent kinetics on these functionalized Fe porphyrins in case you're interested!

D206: Today I'm looking at this interesting assembly from the Nocera group and it's temperature dependent KIEs!.
pubs.acs.org
The temperature-isotope dependence of proton-coupled electron transfer (PCET) for a noncovalent molecular dyad is reported. The system consists of an excited-state Zn(II) porphyrin that transfers an...

D205: Today, I started digging into any literature examples where temperature-dependent studies have been done on PCET systems. I actually couldn't find many papers on it, so if anyone has suggestions let me know!.

Three phenols with pendant, hydrogen-bonded bases (HOAr-B) have been oxidized in MeCN with various one-electron oxidants. The bases are a primary amine (−CPh2NH2), an imidazole, and a pyridine. The...

D204: Rounding out this week with one more N2RR paper!.
pubs.acs.org
Terminal and bridging end-on coordination of N2 to transition metal complexes offer possibilities for distinct pathways in ammonia synthesis and N2 functionalization. Here we elucidate the fundamen...

D203: This is some very interesting work coming from @swierklab on tattoo ink compositions! The introduction alone is a fascinating overview of how strictly/loosely tattoo inks have been regulated in the past up until now. it's pretty eye-opening.
pubs.acs.org
As tattoos continue to rise in popularity, the demand for tattoo ink has surged. Historically, tattoo inks have been underregulated in the US market. This study analyzes inks from nine different...

D202: Here's another cool article on N2RR catalysis using Lewis acids for a push-pull effect!.
pubs.acs.org
We present a systematic investigation of the structural and electronic changes that occur in an Fe(0)–N2 unit (Fe(depe)2(N2); depe = 1,2-bis(diethylphosphino)ethane) upon the addition of exogenous...

D200: Someone asked me if I had something cool planned for number 200. I originally did not, but @AnnMarieMay22 showed me this post last week and I knew I was going to put it as the milestone paper! I love electrochemistry and now you can use it to make music!.
Check out our paper on the Electrochemical Synthesis of Sound in @ACSCentSci! We make sound from the motion of ions at the electrochemical interface, thereby gaining intuitive insight into dynamics occurring at the interface!
