Usage

General Description

N,N',N''-Triphenyl-1,3,5-benzenetriamine, also known as triphenylbenzene-triamine or TPTA, is a chemical compound primarily used as an additive in the production of rubber. It serves as an antioxidant and antiozonant, protecting the rubber material from degradation caused by exposure to oxygen and ozone. TPTA is effective in improving the aging resistance and durability of rubber products, making it a valuable component in the manufacturing of tires, hoses, belts, and other rubber-based goods. Additionally, TPTA has applications in the production of plastics, adhesives, and other synthetic materials, where its antioxidant properties are beneficial for extending the lifespan and performance of the products. However, it should be handled and stored with care due to its potential health and environmental hazards.

Hole-transporting materials for low donor content organic solar cells: Charge transport and device performance

Low donor content solar cells are an intriguing class of photovoltaic device about which there is still considerable discussion with respect to their mode of operation. We have synthesized a series of triphenylamine-based materials for use in low donor co

Glass Formation and Phase Transition of Novel ?-Electron Starburst Molecules, 1,3,5-Tris(phenyl-2-thienylamino)benzene and 1,3,5-Tris(phenyl-3-thienylamino)benzene

Novel ?-electron strburst molecules, 1,3,5-tris(phenyl-2-thienylamino)benzene (α-TPTAB) and 1,3,5-tris(phenyl-3-thienylamino)benzene (β-TPTAB), are found to form amorphous glasses with well-defined glass-transition temperatures of 38 and 46 deg C, respect

Synthesis and photoluminescent properties of geometrically hindered cis-tris(diphenylaminofluorene) as precursors to light-emitting devices

A novel highly luminescent tris-fluorenyl ring-interconnected chromophore tris(DPAF-C9) was synthesized using a C3 symmetrical triaminobenzene core as the synthon. This structure bears three light-harvesting 2-diphenylamino-9,9-dialkylfluorenyl (DPAF) ring moieties with each attached by two branched 3′,5′,5′-trimethylhexyl (C9) arms. A major stereoisomer was chromatographically isolated and characterized to possess a 3D structural configuration of cis-conformer in a cup-form. Molecular calculation at B3LYP/6-31Glevel revealed the unexpected stability of this cis-cup-conformer of tris(DPAF-C9) better than that of the stereoisomer in a propeller-form and the trans-conformer. The structural geometry is proposed to be capable of minimizing the aggregation related self-quenching effect in the condensed phase. Fluorescence emission wavelength of tris(DPAF-C9) was found to be in a close range to that of PVK that led to its potential uses as the secondary blue hole-transporting material for enhancing the device property toward the modulation of PLED performance.

Buchwald-Hartwig Amination of Coordinating Heterocycles Enabled by Large-but-Flexible Pd-BIAN-NHC Catalysts**

A new class of large-but-flexible Pd-BIAN-NHC catalysts (BIAN=acenaphthoimidazolylidene, NHC=N-heterocyclic carbene) has been rationally designed to enable the challenging Buchwald-Hartwig amination of coordinating heterocycles. This robust class of BIAN-NHC catalysts permits cross-coupling under practical aerobic conditions of a variety of heterocycles with aryl, alkyl, and heteroarylamines, including historically challenging oxazoles and thiazoles as well as electron-deficient heterocycles containing multiple heteroatoms with BIAN-INon (N,N′-bis(2,6-di(4-heptyl)phenyl)-7H-acenaphtho[1,2-d]imidazol-8-ylidene) as the most effective ligand. Studies on the ligand structure and electronic properties of the carbene center are reported. The study should facilitate the discovery of even more active catalyst systems based on the unique BIAN-NHC scaffold.
