Indole‐Based π‐Extended Monophosphine Ligands for Enhanced Palladium‐Catalyzed Sonogashira Coupling

Journal of Heterocyclic Chemistry, EarlyView.
A general palladium‐catalyzed Sonogashira cross‐coupling of (hetero)aryl chlorides with aliphatic, (hetero)aryl alkynes is described using Pd(dba)₂/PCy2‐Napdole‐phos catalyst system. The reaction protocol exhibits broad substrate scope and the catalyst loading can be down to 0.2 mol% Pd.

Unravelling the Spatiotemporal Exciton Dynamics in Electrically Pumped Organic Laser Diodes

Laser &Photonics Reviews, EarlyView.
High‐speed OLED measurements combined with advanced simulations reveal how singlet, triplet, and polaron dynamics drive key loss channels that hinder organic semiconductor lasing, while presenting strategies to overcome them. Abstract Organic materials offer wide‐band emission covering regions of the spectrum unachievable by conventional semiconductors.

Fluorescent Polyethers Incorporating Perylene Diimide Derivatives: Investigating a Strategy of Limiting Aggregation

Macromolecular Materials and Engineering, EarlyView.
This work focuses on the use of perylene diimide (PDI) in the main polymeric chain of poly(arylene ether)s. It attempts to unlock the emission of PDI by randomly distributing it along the main chain to avoid quenching. This is a strategy that can be incorporated toward developing materials for the active layer of Polymeric Light Emitting Diodes (PLEDs).

2,3‐Dichloro‐5,6‐Dicyano‐1,4‐Benzoquinone (DDQ)‐Mediated CC Bond Formation: Redox Strategies from Stoichiometric to Catalytic Systems

ChemistryOpen, EarlyView.
2,3‐Dichloro‐5,6‐dicyano‐1,4‐benzoquinone serves as a versatile oxidant and redox catalyst for CC bond formation through hydride abstraction or single‐electron transfer. Stoichiometric and catalytic systems enable benzylic, allylic, and aromatic CH activation under mild, metal‐free conditions, providing sustainable routes to complex and bioactive ...
