p-Bromanil–p-phenylenediamine Complex

Nature, 1963
SEVERAL charge transfer complexes have been examined in this laboratory. This investigation has been concerned with the electrical and magnetic properties of these compounds as well as their syntheses. The p-chloranil–p-phenylenediamine complex has thus far been examined in greatest detail1.

Redox polymers containing p‐phenylenediamine groups

Die Angewandte Makromolekulare Chemie, 1978
AbstractOxidation‐reduction reactions and some applications of polymers containing p‐phenylenediamine skeleton in side branches were studied in aqueous solutions. The polymer was used also for preparation of immobilized enzymes by oxidative coupling reaction.

Covalently functionalized heterostructured carbon by redox-active p-phenylenediamine molecules for high-performance symmetric supercapacitors

New Journal of Chemistry, 2019
p-Phenylenediamine (PPD) as a novel organic electrochemically active material for supercapacitors has been covalently grafted onto dissected carbon nanotubes (DCNTs) via a facile single-step reflux method.

Effective Reduction of p-Nitroaniline to p-Phenylenediamine Using Cu-CuO Nanocomposite

Materials Today: Proceedings, 2019
In the current study, we demonstrate a low cost approach for the facile synthesis of Cu and Cu-CuO nanocomposite by a chemical reduction method. By tuning the chemical constituent in the reaction, we can effectively synthesise metal-semiconductor (Cu-CuO)

High-performance blue fluorescent/electroactive polyamide bearing p-phenylenediamine and asymmetrical SBF/TPA-based units for electrochromic and electrofluorochromic multifunctional applications

Journal of Materials Chemistry C, 2019
A novel EC/EFC polyamide is realized by introducing stably electroactive p-phenylenediamine and asymmetrical SBF/TPA-based unit to reduce packing.

Histochemical Demonstration of Aldehydes by p-Phenylenediamine

Nature, 1961
A HIGHLY specific and sensitive reaction has already been proposed1 for the microscopic detection of aldehydes in the tissues. Improvements have now been made which meet the needs of practical histochemistry.

Ring-Alkylated p-Phenylenediamines as Antiozonants

Rubber Chemistry and Technology, 1963
Abstract As part of a larger program to correlate the antiozonant activity of rubber additives with their chemical structure, we investigated a homologous series of ring-alkylated p-phenylenediamines. It seemed to us that such investigation might possibly determine whether or not a primary diamine could be an effective antiozonant.

Final Report on the Safety Assessment of N-Phenyl-p-Phenylenediamine, N-Phenyl-p-Phenylenediamine Hydrochloride, and N-Pheny 1-p-Phenylenediamine Sulfate

Journal of the American College of Toxicology, 1994
N-Phenyl-p-Phenylenediamine and its sulfate and hydrochloride salts are aromatic amines. Whereas N-Phenyl-p-Phenylenediamine Sulfate is not currently reported to be used in cosmetics, N-Phenyl-p-Phenylenediamine and N-Phenyl-p-Phenylenediamine Hydrochloride are used as colorants in hair dyes/colors.
