“…This value is very close to that of 4-methyltriphenylamine (5.64 eV), slightly higher than that of TPD (5.50 eV) and noticeably higher than that of poly(4-alkyltriphenylamine) (5.29-5.30 eV) [20]. The ionisation potential values for charge generation materials, including those widely used in electrophotographic photoreceptors, such as titanyl phthalocyanines [21,22], perylene pigments [23] and bisazo pigments [24] are in the range of 5.1-5.6 eV.…”

Abstract-Synthesis and cationic photopolymerization of new triphenylamine-based oxiranes, i.e., 4-[(oxiranylmethoxy) methyl] triphenylamine, 4-hydroxymethyl-4 -(2-oxiranylmethoxymethyl) triphenylamine and 4-[4-(oxiranylmethoxymethyl) phenylphenylamino]-4 -(diphenylamino) biphenyl are reported. Di-(tert-butylphenyl) iodonium tetrafluoroborate (BPIT), diphenyliodonium tetrafluoroborate (DPIT) and (η 5 -2,4-cyclopentadien-1-yl) [1,2,3,4,5-η)-(1-methylethyl) benzene]-iron (+)-hexafluorophosphate (−1) (Irgacure 261) were used as photoinitiators. These photopolymerizations give products with a degree of polymerization varying between 4 and 108. The photopolymerization of the triphenylamine based hydroxyl group containing oxirane apparently occurs by activated monomer mechanism in its final stage. Photopolymerization of 4-[(oxiranylmethoxy) methyl] triphenylamine was studied in more detail. The influence of photoinitiator, temperature, and photoinitiator concentration on the rate of polymerization and conversion limit is discussed.

“…2. (PTPA is gained by chemical polymerization 12 ). According to the spectrum of PEDOT, the bands at 1513, 1322 and 1195 cm −1 originate from the stretching modes of C=C and C-C in the thiophene rings (Fig.2a), the bands at 1084 and 980 cm -1 arise from the stretching modes of C-O-C and C-S-C in EDOT rings, respectively.…”

Copolymer based on triphenylamine (TPA) and 3,4-ethylenedioxythiophene (EDOT) is polymerized electrochemically. The structure, morphology and electrochemical properties of the obtained copolymer are investigated by cyclic voltammetry and FT-IR spectroscopy. The results confirm the copolymerization of TPA/EDOT. UV-vis spectra show that the absorption peaks of the copolymer are different from those of Polytriphenylamine. Moreover, photoluminescence spectra of the copolymer exhibit great changes in emission color from pale blue to pale green with the variety of ratio of two monomers. Therefore, the monomer feed ratio plays important roles in the optical property of this copolymer.

“…Especially, the polymeric TAA derivatives exhibit extensive application prospects due to the potential advantages such as possibility of extended -conjugation and excellent film-forming property. The common reactions for the synthesis of poly(triarylamine) (PTAA) where TAA units are linked together in the main chain are Ullman reaction [5], palladium or nickel catalyzed coupling reactions [6], and simple oxidative polymerization using ferric chloride as an oxidizing agent [7,8]. Recently, our group have.…”

Poly(4-butyltriarylamine)s with t-butyldimethylsilyl terminal protecting group (PBTPA-TBS) with various molecular weights were prepared by C-N coupling polymerization. The resulting precursors were postfunctionalized and subsequently used as macroinitiators for atom transfer radial polymerization (ATRP) of n-butyl acrylate (n-BA) and ethyl acrylate (EA). Both the polymerization processes were controlled and the polymers were characterized by 1 H NMR, gel permeation chromatography (GPC) and thermal properties, which confirmed the successful synthesis of all the polymers. The microphase separated behaviors of the poly (4-butyltriarylamine)-block-poly (butyl acrylate) (PBTPA-b-PBA) were examined by AFM in the film showing phase separation structures for all the polymers. The photorefractive property of the composite based on PBTPA-b-PBA block copolymer was evaluated by two-beam coupling experiment. A relative high gain coefficient of 42.7 cm −1 was obtained at the electric field of 31 V/m.
