Preparation and properties of diacridine/diacridinium compounds possessing a spacer with different rigidity.

Abstract

Dichromophoric motifs exhibit special properties which the corresponding monochromophoric counterpart does not. Such properties largely depends on the distance and relative orientation of two chromophores. 9-Phenylacridine and 10-methyl-9-phenylacridinium have been known for their redox activity and fluorescent properties. We studied the compounds having two 9-phenylacridines and 10-methyl-9-phenylacridiniums, which are linked by a spacer with different rigidity. The rigidity of spacers affects their spectra properties and redox behaviors, whose details will be reported.
