Two New Acridone Alkaloids from Glycosmis macrantha [PDF]
Molecules, 2011 Extraction and chromatographic separation of the extracts of dried stem barks of Glycosmis macrantha lead to isolation of two new acridone alkaloids, macranthanine (1) and 7-hydroxynoracronycine (2), and a known acridone, atalaphyllidine (3).

N-Aryl Acridone Derivatives as Effective Catalysts for Energy Transfer Reactions. [PDF]
ChemistryAcridones derivatives have high triplet energy, are simple accessible, and could be used in challenging [2+2] ENT reactions. ABSTRACT Organic photocatalysts capable of promoting high‐energy triplet energy transfer (EnT) remain limited, particularly for demanding [2+2] photocycloaddition reactions.

A Metallosupramolecular Receptor for Squaraine Dyes Enabling Ultrafast Dark Resonance Energy Transfer. [PDF]
Angew Chem Int Ed EnglA metallosupramolecular receptor binds squaraine dyes with high affinity and enables efficient dark resonance energy transfer (DRET) that generates bright near‐infrared emission with large pseudo‐Stokes shifts. ABSTRACT A metal‐organic cage was obtained by combining acridone‐based dipyridyl ligands with Pd2+ ions. The cage acts as a potent receptor for
