Wide-Range Color-Tunable Organic Phosphorescence Materials for Printable and Writable Security Inks

Organic materials with long-lived, color-tunable phosphorescence are potentially useful for optical recording, anti-counterfeiting, and bioimaging. Herein, we develop a series of novel host–guest organic phosphors allowing dynamic color tuning from the cy

Palladium-catalyzed ligand-free and aqueous Suzuki reaction for the construction of (hetero)aryl-substituted triphenylamine derivatives

This paper reports an efficient synthesis of triphenylamine (TPA) derivatives via a palladium-catalyzed Suzuki reaction of (hetero)aryl halides with 4-(diphenylamino)phenylboronic acid (DPBA) in aqueous ethanol under aerobic and ligand-free conditions. Heteroaryl halides, namely pyridyl bromides, quinolyl bromides, pyrimidinyl bromides, 2-chloropyrazine and sulfur-containing heteroaryl bromides, could react smoothly with DPBA, affording good to excellent yields under mild conditions. In addition, aryl bromides were also successfully employed in the cross-couplings with DPBA and furnished the products in high yields at room temperature. The cross-coupling of 4-bromobenzonitrile with DPBA gave the desired product in a quantitative yield within 2 min, resulting in a TOF up to 5820 h-1.

Very fast, ligand-free and aerobic protocol for the synthesis of 4-aryl-substituted triphenylamine derivatives

A fast, convenient and ligand-free protocol for the synthesis of a series of 4-aryl-substituted triphenylamine derivatives by a palladium-catalysed aerobic Suzuki reaction of aryl halides with [4-(diphenylamino)phenyl]boronic acid in aqueousiPrOH is described. Importantly, both aryl bromides and heteroaryl halides afforded good to excellent yields under mild conditions. A facile, efficient and general ligand-free Suzuki reaction in aqueous iPrOH is described. Under the optimized conditions, both aryl bromides and heteroaryl halidesreacted rapidly with [4-(diphenylamino)phenyl]boronic acid, providing a series of 4-aryl-substituted triphenylamine derivatives in good to excellent yields.

Synthesis and characterisation of substituted diphenylamines - Charge-transfer, donor-acceptor systems localised at water-oil interfaces

A range of charge-transfer, donor-acceptor systems have been synthesised and subjected to in-depth crystallographic, spectroscopic and interfacial studies. The pyridine- or phenyl-substituted (N,N-diphenyl)amino derivatives contain an identical donor unit
