Acridones: Strongly Emissive HIGHrISC Fluorophores

The Journal of Physical Chemistry Letters, 2021
An 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.

9(10H)-Acridone

Acta Crystallographica Section C Crystal Structure Communications, 1995
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

Acridone studies. VI. Bromination of acridones in chloroform

Australian Journal of Chemistry, 1969
In 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

Equilibrium NH acidities of acridan, phenanthridone, 9-acridone, and substituted 9-acridones

Chemistry of Heterocyclic Compounds, 1982
The equilibrium NH acidities of acridan, phenanthridone, 9-acridone, and 2-substituted 9-acridones (substituents: Me2N, MeO, F, Br, I, and NO2) were measured by transmetallation in dimethyl sulfoxide (DMSO). The role of conjugation and the aromatic character of the heterocyclic ring in stabilization of the anions is discussed.

Acridone Alkaloids

2017
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 ...

New Acridone Alkaloids from Citrus Plants

HETEROCYCLES, 1992
The spectroscopic structure elucidations of five new acridone alkaloids named yukocitrine (1), yukodine (3), Yukodinine (4), grandisine-III (6) and pummeline (7) from some Citrus plants were ...

Quinoline, quinazoline, and acridone alkaloids

Natural Product Reports, 1984
The most interesting new alkaloids are the acridones that contain tropone rings, which have been isolated from Citrus species. Emphasis this year is again on synthesis, with highlights including the first use of copper acetylides in the synthesis of furoquinolones, the synthesis of the (1,l -dimethylallyl)quinolinone buchapine, and developments in the ...

Biomimetic synthesis of acridone alkaloids

Journal of the Chemical Society, Perkin Transactions 1, 1977
Cyclisations of 2′-amino-, 2′-acetylamino-, or 2′-methylamino-2-methoxybenzophenones occur in the presence of sodium hydride in dimethyl sulphoxide to give acridone alkaloids. This cyclisation has relevance to the biosynthesis of these alkaloids. An alternative cyclisation can occur, giving 4-arylquinolines or 4-arylquinolones.
