The Solid‐State Emission of AIPE‐Active Tricarbonylrhenium(I) Complexes Shifts to the Red: The Unexpected Performance of Triphenylphosphine Derivatives

Aggregate, Volume 7, Issue 7, July 2026.
New phosphino tricarbonylrhenium(I) complexes have efficient red emission in the aggregate and solid states. The good photostability and the vast possibilities of chemical modifications make these Re‐based complexes the starting point of a new generation of red emitters with aggregation‐induced phosphorescence emission (AIPE) characteristics.

Enhancing Interfacial Charge Transport in Gold Nanoparticle@Polyaniline Hybrids via N‐Heterocyclic Carbene Linkers

Angewandte Chemie, Volume 138, Issue 26, 22 June 2026.
An amino‐functionalized NHC‐Au complex is employed as a conductive molecular linker to couple large Au NPs with PANI, yielding Au NP@NHC‐PANI hybrids with an electronically well‐defined interface. SAMs of these hybrids reveal enhanced charge transport compared with Au NP@PANI.

Unlocking Catalyst Activation as a Critical Bottleneck in Cross‐Coupling Reactions: Room‐Temperature Couplings of Weak Nucleophiles Enabled by [Pd(1‐MeNAP)TFA]2 Precatalysts

Angewandte Chemie International Edition, Volume 65, Issue 27, 1 July 2026.
In many Pd‐catalyzed cross‐couplings, catalyst performance has been found to be limited by catalyst activation. Methylnaphthyl (MeNAP) palladium trifluoroacetate dimers are presented as easy‐to‐store and easy‐to‐handle precursors, which rapidly activate under reaction conditions, even when only weakly coordinating, non‐reducing nucleophiles are present.

N-heterocyclic carbenes : synthesis and applications [PDF]

, 2015
N-Heterocyclic carbenes (NHCs) are powerful tools in organic chemistry, with numerous applications in academic and industrial laboratories. They are usually defined as singlet carbenes, in which the divalent carbonic centre is connected directly to at ...

NH Bond Activation of Hydrazine Using Cyclic (alkyl)(amino)carbenes and Boranes

ChemistryEurope, Volume 4, Issue 7, July 2026.
EtcAAC activates the NH bond of phenyl‐substituted hydrazines, forming EtcAAC(H)(N2HnPh3‐n) (n = 1–2). In contrast, the reaction between EtcAAC and unsubstituted hydrazine (N2H4) undergoes further decomposition. Productive NH activation of N2H4 is achieved by incorporating boranes both inter‐ and intramolecularly, leveraging their distinct binding ...

When Dark States Become Bright: Vibronic Intensity Borrowing in Triplet 2,6‐Dichloro‐4‐Hydroxyphenylnitrene

Journal of Physical Organic Chemistry, Volume 39, Issue 7, July 2026.
Irradiation of 4‐azido‐2,6‐dichlorophenol in cryogenic matrices generates triplet 2,6‐dichloro‐4‐hydroxyphenylnitrene. Vibronically structured absorption enables extension of a formally forbidden transition into the visible region (up to 500 nm). Analyses based on NICS(1.7)zz, ACID, HOMA, MCI, and spin density reveal magnetically induced ring currents ...
