Current study of citrus acridone is focusing on the tissue of root and stem, and there is no report on the study of fruit acridone up to now.
Theirelec-tron affinities, measured by cyclic voltammetry, indicated that all these acridone derivatives could be reduced easily and had higher electron affinities than2-(4- biphenyl)-5-( t-butylphenyl)-1,3,4- oxadiazole( PBD), a typical electron-transfer material.
