, p. 1007 - 1015 (2007)
A 4-methoxy-substituted triphenylamine containing the aromatic diamine, 4,4′-diamino-4″-methoxytriphenylamine (2), was synthesized by the caesium fluoride-mediated condensation of p-anisidine with 4-fluoronitrobenzene, followed by palladium-catalyzed hydr

Linear and hyperbranched poly(azomethine)s (PAMs)-based on triphenylamine moieties are synthesized and used as the functioning layers in the Ta/PAM/Pt resistive switching memory devices. Comparably, the hyperbranched PAM with isotropic architecture and semi-crystalline nature shows enhanced memory behaviors with more uniform distribution of the HRS and LRS resistances.
Construction of electrocatalytic electrodes bearing the triphenylamine nucleus covalently bound to carbon. A halogen dance in protonated aminotriphenylamines
Mayers, Brian T.,Fry, Albert J.
, p. 411 - 414 (2006)
The triarylamine nucleus has been attached to a carbon fiber electrode by diazotization of an aminotriphenylamine followed by electrochemical reduction. The resulting electrodes can electrocatalyze the oxidation of organic substrates. In acid, 4-amino-4′,4″-dibromotriphenylamine undergoes dismutation into a mixture of amines containing from 0 to 3 bromine atoms.
Structural characterization of triphenylamine (TPA)-based polymers during the oxidative reaction by two-dimensional (2D) infrared correlation study
Bae, Jun,Chae, Boknam,Seo, Hyemi,Jung, Young Mee,Lee, Seung Woo
, p. 200 - 204 (2014)
This paper reports the oxidative reaction of triphenylamine (TPA)-based polyamide films. A two-dimensional (2D) gradient mapping method and 2D correlation analysis were applied to the ultraviolet-visible (UV-Vis) and infrared (IR) spectra of TPA-based pol

A new triphenylamine-containing aromatic diamine, N,N-bis(4-aminophenyl)-N′,N′-diphenyl-1,4-phenylenediamine, was synthesized from the animation reaction between 4-aminotriphenylamine and 4-fluoronitrobenzene and subsequent reduction of the dinitro intermediate. A series of novel aromatic poly(amine-imide)s with pendent triphenylamine units were prepared from the newly synthesized diamine and various tetracarboxylic dianhydrides by either a one-step or a conventional two-step polymerization process. All the poly(amine-imide)s were amorphous and readily soluble in many organic solvents such as N-methyl-2-pyrrolidone (NMP), N,N-dimethylacetamide, and chloroform. These polymers could be solution cast into transparent, tough, and flexible films with good mechanical properties. They had useful levels of thermal stability associated with relatively high glass transition temperatures (264-3520°C), 10% weight-loss temperatures in excess of 568°C, and char yields at 800°C in nitrogen higher than 63%. These polymers exhibited strong UV-vis absorption bands at 311-330 nm in NMP solution. The photoluminescence spectra showed maximum bands around 545-562 nm in the green region. The holetransporting and electrochromic properties are examined by electrochemical and spectroelectrochemical methods. Cyclic voltammograms of the poly(amine-imide) films cast onto an indium-tin oxide (ITO)-coated glass substrate exhibited two reversible oxidation redox couples at 0.78 and 1.14 V versus Ag/ AgCl in acetonitrile solution. The poly(amine-imide) films revealed excellent stability of electrochromic characteristics, with a color change from the pale yellowish neutral form to the green and blue oxidized forms at applied potentials ranging from 0.78 to 1.14 V.
Isolable Adducts of Tertiary Amines and Dinitrogen Trioxide
Rosadiuk, Kristopher A.,Scott Bohle
, p. 4543 - 4549 (2018/10/31)
Anhydrous dinitrogen trioxide, N2O3, dissolved in toluene or dichloromethane rapidly forms stable adducts with tertiary amines such triethyl-, tribenzyl-, or trihexyl-amine. With DABCO, 1,4-diazabicyclo[2.2.2]octane it forms a free flowing orange solid. The analytical and spectroscopic data for the DABCO adduct indicate a formula of DABCO(N2O3)2 which has been characterized by IR, Raman, and UV/Vis spectroscopy. The R3N-N2O3 adducts are hydrolytically sensitive oils or solids which rapidly react quantitatively with thiols to give RSNO. The reactivity of the amine adducts is variable, and the products include amine N-oxides, ammonium nitrites, and ammonium nitrates depending upon the adduct, conditions, and substrate. Density functional theory, B3LYP/aug-cc-pvtz, has been used to compare the predicted structures and spectroscopic data for mono and bis adducts. Geometry optimization of the R3N N2O3 adduct gives a weakly bound Lewis acid/base adduct with the amine nitrogen closest to the nitrosyl N with a strongly tilted planar ONNO2 unit.
