Synthesis of organic compounds of arsenic: the preparation of acridone arsonic acids [PDF]

, 1934
I. The P'reuss and Binz reaction, i.e. the conversion of o- nitrotoluene to anthranilic acid by concentrated alkali, has been extended to 3- nitro4- methylphenyla.rsonic with the formation of 3- amino4- carboxyphenylarsonic acid.II.

The Theoretical Description for a Sucralose Electrochemical Cathodical Determination over a 9-9´-Diacridyl-modified Electrode

Orbital: The Electronic Journal of Chemistry, 2021
A novel electroanalytical process for sucralose determination has been theoretically suggested. Sucralose is immobilized over an acridine derivative 9-9´-diacridyl, yielding a quaternary salt, which is thereby gradually electrochemically reduced to an N-

Color‐Pure Organic Luminophores: Characteristics, Definitions, Physical Basis and Fundamental Design Principles

Angewandte Chemie, Volume 138, Issue 30, 20 July 2026.
Color‐pure all‐organic emitters, i.e., with narrow spectral characteristics, are intensively studied for high‐definition organic LEDs and multi‐color bioimaging. In order to guide targeted materials design, this educative review discusses spectral characteristics, proper definitions and units, and the physical basis of spectral broadening, to distill ...

Acridone-based acetylcholinesterase inhibitors: synthesis, antioxidant activity and molecular modeling [PDF]

, 2018
Acridone is a unique naturally occurring alkaloid known to associate with several biological activities. 2,3-dimethoxy-10-methyl-10,8a-dihydroacridin-9(8aH)-one (4) and its precursor 2-((3,4-dimethoxyphenyl)methylamino)benzoic acid (3) were synthesized ...
