چکیده

Literature survey reveal that a good number of Anthracene and substituted Anthracene are potential lasing organic compounds. As per mit suo meada66 9,10-dimethyl and 9,10-diphenyl Anthracenes exhibit lasing properties, around 435-450 nm (ethanol). In continuation of our studies in this lab, our objective is to synthesize new lasing organic dyes, in particular, new Anthracene derivatives and study their photo physical properties, besides the lasing characterization. 2,6-disubstituted or 2,5 – di-substituted Anthracenes are our choice. Hence, it is proposed to synthesize 2-Methoxy, 5-nitro, 9, 10-Anthraquinone and to examine whether these type of molecules also exhibit lasing properties. Initially it is preferred to study the photo physical properties for better understanding of the lasing phenomena. The synthetic route for the synthesis of 2-Methoxy, 5-nitro, 9,10-Anthraquinone is described below in (Scheme -1).
