A comparative study on the properties of aromatic polyamides with methyl- or trifluoromethyl-substituted triphenylamine groups

Two triphenylamine-based diamine monomers, 4,4′-diamino-4″-methyltriphenylamine and 4,4′-diamino-4″-(trifluoromethyl)triphenylamine, were synthesized via the cesium fluoride-mediated double N-arylation reactions of p-toluidine and p-(trifluoromethyl)anili

Base-promoted nucleophilic fluoroarenes substitution of C–F bonds

With the use of KOH/DMSO as the superbase medium, the nucleophilic fluoroarene substitution for C–F bonds is presented. The transformation proceeds smoothly with the use of fluoroarenes bearing not only electron-withdrawing group, but also electron-donating group and a variety of nucleophiles such as alcohols, phenols, amines, amides and nitrogen-heterocyclic compounds. The double nucleophilic substitution using ortho-difluoroarenes and nucleophiles bearing ortho-dinucleophilic groups results in the formation of 2,3-dihydro-1,4-benzodioxins, dibenzo[b,e][1,4]dioxins and 10H-phenoxazines in moderate to good yields.

C-N cross-coupling reaction catalysed by reusable CuCr2O4 nanoparticles under ligand-free conditions: A highly efficient synthesis of triarylamines

A convenient, efficient and ligand-free method for the C-N coupling reaction of anilines and aryl iodides was performed using CuCr2O4 nanoparticles. Copper chromite nanocatalyst improved the rate and facility of the synthesis of triarylamines. The heterogeneous catalyst was fully characterized by scanning electron microscopy, IR and X-ray diffraction techniques. Recyclability, excellent yields of products and short reaction times are the important advantages of this ligand-free procedure by using the CuCr2O4 nanoparticles. This journal is

Synthesis and electrochromic, acidochromic properties of Schiff bases containing triphenylamine and thiophene units

A series of Schiff bases (SBs) were designed and prepared from 2-thiophenecarboxaldehyde and different triphenylamine (TPA) derivatives. The structures of the compounds were characterized by Fourier transform infrared (FT-IR), hydrogen nuclear magnetic resonance (1H NMR). The optical and electrochemical properties were tested by ultraviolet-visible (UV-vis) spectroscopy and cyclic voltammetry (CV) techniques. The SBs exhibited stable and reversible electrochromic properties. Furthermore, multiple reversible colors states were also observed with the change of pH. Consequently, the SBs can be used as electrochromic and acidochromic materials.

A convenient and efficient synthesis of triarylamine derivatives using CuI nanoparticles

We report a simple and efficient method for the synthesis of triarylamine derivatives using copper iodide nanoparticles, 1,10-phenanthroline and potassium hydroxide. Copper iodide nanoparticles enhanced the rate and ease of reaction and exhibited a high influence in the efficient synthesis of various amine derivatives. The nanoparticles also increased the yields of products and decreased the reaction times in all cases. The heterogeneous mediator was fully characterized by scanning electron microscopy and X-ray diffraction techniques.

Electrochromism properties of polyimides possessing triphenylamine moieties with different substituents

Two diamine monomers with methyl (CH3TPA) and methoxy (OCH3TPA) group substituents in the para position of the triphenylamine (TPA) moiety were synthesized by nucleophilic aromatic substitution using 4-fluoronitrobenzene with p-toluidine and p-anisidine,

Synthesis and unexpected electrochemical behavior of the triphenylamine-based aramids with ortho-and para-trimethyl-protective substituents

Two series of new organosoluble polyamides with methyl-substituted triphenylamine (MeTPA) units showing anodically electrochromic characteristic were prepared from the phosphorylation polyamidation reaction of two diamine monomers, 4,4′-diamino-2″,4″,6″-trimethyltriphenylamine (Me3TPA-diamine; 2) and 4,4′-diamino-4″- methyltriphenylamine (MeTPA-diamine; 2′), with various dicarboxylic acids, respectively. These polymers were readily soluble in many polar solvents and showed useful levels of thermal stability associated with relatively high glass-transition temperatures (Tg) (314-329 °C) and high char yields (higher than 62% at 800 °C in nitrogen). In addition, the polymer films showed reversible electrochemical oxidation, high coloration efficiency (CE), low switching time, and anodic green electrochromic behavior. The unexpected electrochemical behavior of higher oxidation potential and lower electrochemical stability of Me3TPA-polyamides I than MeTPA corresponding polymers could be attributed to the higher steric hindrance of ortho-substituents in Me3TPA moieties, thus made the resonance stabilization of cation radical much more difficult for the Me 3-substituted phenyl ring.
