- Highly emissive organic solids with remarkably broad color tunability based on N,C-chelate, four-coordinate organoborons
-
Molecular fluorophores based on N,C-chelate, four-coordinate organoborons exhibit tunable solid-state emission colors that cover the whole visible region from blue to red. The emission color can be tuned through the substituents on either quinolines or the boron center.

- Based on pyridine ring metal-ligand-platinum complex and its preparation method and application
-
The invention relates to a novel cyclometal ligand-platinum complex and a preparation method and application thereof, and belongs to the technical field of electronic materials. The novel cyclometal ligand-platinum complex is convenient in template design and easy to obtain. Triphenylaminyl, quinolyl and trifluoromethyl are introduced in a material, and the electron structure and the hole injection and transmission performance of the material can be conveniently adjusted by adjusting substituents on an aza heteroaromatic ring. The complex provided by the invention is good in thermal stability and hole injection and transmission performance, and has wide application prospect in the fields of organic electroluminescent materials, oxygen sensing materials, dyes and medicines and the like. The oxygen sensor prepared by the complex has the advantages of simple structure, low cost, reliable work and the like; and the complex can be prepared into a portable oxygen sensor to be popularized and used.

- 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.
