Imidazo[1,5‐a]pyridines – A Versatile Platform for Structurally Distinct N‐Heterocyclic Olefins and π‐Extended Heterocycles

open access: yesAngewandte Chemie International Edition, EarlyView.
The synthesis of N‐heterocyclic olefins (NHOs) based on an imidazo[1,5‐a]pyridine scaffold is described. While C5‐alkyl or aryl substituents yield stable NHOs, alkenyl or alkynyl groups at C5 induce 6‐endo cyclization to form (dihydro)imidazo[2,1,5‐de]quinolizines with strong paratropic ring currents.

Orientation‐Dependent Upper Critical Magnetic Field and Density of State for Uranium Ditelluride

open access: yesAdvanced Physics Research, EarlyView.
This study investigates the orientation‐dependent upper critical magnetic field (HC2) and the density of states (DOS) in the unconventional superconductor UTe2. These results reveal an anisotropic HC2, with distinct critical fields along different crystallographic axes, highlighting the role of electronic correlations and spin‐triplet pairing.

Cyclopentannulated Decacyclenes as Carbon‐Based Multistage Electron Acceptors

open access: yesChemistry – An Asian Journal, EarlyView.
A series of cyclopentannulated decacyclenes were synthesized in a modular approach. Subsequent cyclization allowed the expansion of the π‐system. The carbon‐based compounds undergo up to six reversible reductions within an impressively narrow potential range between −1.45 and −2.86 V under electrochemical conditions.
