Acridinediones have been identified as antimalaria [1] and antitumor agents [2]. Decahydroacridine-1, 8-dione derivatives have been reported to have high fluorescence efficiency and can be used as fluorescent molecular probes for monitoring of polymerization process [3]. Furthermore, the acridinedione dyes have already been reported as a class of laser dyes operating in the bluegreen region [4]. They are also receiving much attention ...
