Acridone studies. VI. Bromination of acridones in chloroform
Australian Journal of Chemistry, 1969In chloroform and acetic acid, N-methylacridone and methoxylated derivatives rapidly form 1 : 2 adducts with bromine, formulated as hypobromite salts. On gentle warming these decompose to the monobromo substitution product. Hydroxylated acridones appear to also add bromine to the substituted ring, forming products which are highly reactive to water and

Acridones: Strongly Emissive HIGHrISC Fluorophores
The Journal of Physical Chemistry Letters, 2021An acridone derivative (N-methyl-difluoro-acridone, NMA-dF) is characterized with respect to its utility as an emitter in organic light emitting diodes (OLEDs). Using steady-state and time-resolved spectroscopy as well as quantum chemistry, its ability to convert singlet and triplet excitons into light was scrutinized.

The ultraviolet spectra of the acridone alkaloids and some derivatives have been studied. The various bands in the spectra of these compounds are interpreted by starting with theoretical treatments of the spectrum of anthracene and tracing spectral changes through acridine and phenazine to acridone.

The molecular packing arrangement in C 13 H 9 NO is characterized by two major interaction types. The first comprises N−H...O hydrogen bonds between glide-related molecules, with an N...O distance of 2.782 (3) A, such that each molecule is hydrogen bonded to two adjacent molecules. The second consists of π−π interactions between molecules stacked along

There have been substantial developments in the chemistry and biology of the acridone alkaloids in the 16years since the topic was last reviewed in this series of monographs (2000). The present survey covers the literature from mid-1999 to 2016. A brief overview of the biosynthesis of acridone alkaloids is followed by details of the occurrence and ...

The mass spectra of 34 acridones have been determined and interpreted with the aid of both high-resolution measurements and deuterium labelling studies. The spectra contain pronounced molecular ions and are free of skeletal rearrangement fragments. The fragmentation patterns are dependent on the nature and position of substituents, and therefore mass ...

The biogenesis of acridone alkaloids
Journal of the Chemical Society D: Chemical Communications, 1970The similarity in substitution pattern between xanthones and acridone alkaloids and the analogous cyclisation reactions observed for 2-hydroxy- and 2-amino-benzophenones suggest that related biogenetic pathways may be involved.
