Fluorometric Study on the Metal Chelates of Flavone Derivatives. I. Correlation between Fluorescence Intensity and Structure of Beryllium Chelates

Abstract

The correlation between the structure and fluorescence intensity of flavone derivatives and their beryllium chelates was investigated. The ligands of type I, II in Chart 1 and their beryllium chelates did not produce fluorescence, while the ligands of type III, IV fluoresced by themselves and formed fluorescent chelates with beryllium ion. The ligands of type V which were non-fluorescent ligands formed fluorescent beryllium chelates.
