Quadruple hydrogen-bonding interactions stabilized the mixed-valence states of dimers of triarylamine derivatives bearing an ureido pyrimidinedione moiety without any electronic coupling. This study represents the first example of proton-coupled "organic"

Page/Page column 3-4, (2010/07/08)
A pentaaryldiamine-containing bismaleimide compound of Formula (I): is provided, wherein Ar1 to Ar5 are independently C6-C12 aryl, and Ar4 and Ar5 may be optionally substituted. The compound of Formula (I) is obtained by steps of reacting diamine with maleic anhydride in a solvent to form an amic acid, and cyclodehydrating the amic acid in the presence of a catalyst and a dehydrating agent. The compound of Formula (I) with a nonlinear and asymmetric structure is amorphous and is readily soluble in a variety of organic solvents, such that the toughness of the product made therefrom can be improved and processing of the compound can be simplified. Furthermore, the compounds of Formula (I) having cyano substituents on the aromatic ring may exhibit better flame retardancy and heat resistance, higher oxidative stability, electron-withdrawing property etc., such that these compound have wider application in industry.

A series of electrochromic aromatic hyperbranched polyamides with electroactive triphenylamine (TPA) units were prepared from the phosphorylation polyamidation reactions of a newly A2B type monomer, 4-amino-4′,4″-dicarboxytiphenylamine, with AB
The Synthesis of Di- and Tri-arylamines through Halogen Displacement by Base-activated Arylamines: Comparison with the Ullmann Condensation
Gorvin, John H.
, p. 1331 - 1336 (2007/10/02)
In dipolar aprotic solvents, nitranions derived from anilines of enhanced N-acidity displace fluorine from activated aromatic compounds at room temperature.Diarylamines thus produced are free from triarylamines, which are formed at higher temperatures when diarylamines, after N-deprotonation by potassium t-butoxyde or by the heavier alkali metal carbonates, similarly displace activated fluorine.Certain diarylamines can also be prepared by chlorine displacement in the presence of alkali metal carbonates.It is confirmed that such carbonates play only an auxiliary role in the Ullmann (copper-assisted) diarylamine synthesis conducted in dipolar aprotic solvents; they may indeed impede the reaction in some instances.
