Forcing the Side‐on π‐Coordination of a C≡C Triple Bond to Technetium Using the As,CC,As Alkyne Pincer Ligand 1,2‐Bis(2‐(diisopropylarsaneyl)‐4‐(trifluoromethyl)phenyl)Ethyne

open access: yesAngewandte Chemie International Edition, EarlyView.
Technetium alkyne complexes have eluded isolation for decades with the only indicators for their existence being the isolation of vinylidene carbenes or their follow‐up reaction products despite plentiful of reports for neighboring elements. Stable, crystalline Tc(III) and Tc(V) alkyne complexes (and their Re analogs) have now been prepared and fully ...

Reduction of CO2 and Related Compounds with a Low‐Valent CaI Synthon

open access: yesChemistryEurope
The reduction of CO2 with low‐valent s‐block metal complexes is limited to MgI reducing agents. Herein, the reduction of a series of CX2 reagents (X = O, S, NiPr) with the CaI synthon [(BDI)Ca(THP)]2(N2) (VI) is described, which is a CaII complex that ...

N‐heterocyclic carbene‐based tetradentate Pt(II) phosphors for blue organic light‐emitting diodes: Molecular design, photophysics, and device performance

open access: yesBulletin of the Korean Chemical Society, EarlyView.
Structure‐oriented design of NHC‐based tetradentate Pt(II) complexes offers narrowband deep‐blue emission for OLEDs. This review highlights how steric shielding and electronic modulation regulate intermolecular interactions, excited‐state dynamics, and device performance, outlining design principles and outlines toward efficient and durable blue ...

Boosting Electron‐Hole Charge Separation in CO2 Photoreduction through Fluoroporphyrin‐Linked Nickel(II)‐Acetylide Frameworks

open access: yesCarbon Energy, EarlyView.
A NiII‐acetylide framework, H2TFPP‐Ni‐AF, demonstrates outstanding photocatalytic CO2 reduction performance: 13.16 mmol h−1 g−1 of CO with 97.9% selectivity. Synergistic interactions, including d‐p orbital hybridization within NiII‐bis(acetylide) moieties ( − C ≡ C−NiII(PBu3)2 − C ≡ C − ) and the efficient charge transport afforded by π‐conjugated ...

LMCT-driven electron relay unlocks alcohols as tunable reductants for nickel-catalyzed cross-electrophilic couplings

open access: yesNature Communications
Photoinduced electron transfer is fundamental to both biological and synthetic processes; however, modulating back electron transfer (BET) remains a formidable challenge in achieving more efficient photocatalytic transformations. In this work, we present
