An Ultrafast Time Resolved Infrared and Computational Study of the Photochemistry of Ethyl 2‐Diazo‐3,3,3‐Trifluoropropanoate (CF3CN2CO2Et)

Journal of Physical Organic Chemistry, Volume 39, Issue 8, August 2026.
The photochemistry of ethyl 2‐diazo‐3,3,3‐trifluoropropanoate shows that its excited singlet state undergoes internal conversion, carbene formation, and diazirine formation. The resulting singlet carbene reacts through solvent‐dependent pathways, forming ylides in methanol and acetonitrile or a C–Cl insertion product in chloroform.

A Hydrogen‐Bonded Organic Biradical in the Gas Phase

Journal of Physical Organic Chemistry, Volume 39, Issue 7, July 2026.
Hydrogen‐bonded dimers of the TEMPOL radical are investigated by vibrational spectroscopy in the gas phase and shown to occur in at least two conformations, a stretched one with a strong hydrogen bond to the radical centre and a bent one with more pronounced London dispersion interactions. ABSTRACT Persistent organic radicals from the TEMPO family such

Synthesis, Solubilization, and Photophysical Properties of Polyfluorinated Pentacene Dimers

Journal of Physical Organic Chemistry, Volume 39, Issue 7, July 2026.
The synthesis and photophysical analysis of polyfunctionalized pentacene dimers is described. Polyfluorination is employed to modulate the polarizability and to investigate the effects on the mechanism of singlet fission (SF). ABSTRACT A polyfluorinated pentacene dimer, linked with a 1,3‐diethynylphenylene spacer, was synthesized to investigate the ...
