ABSTRACT:

Literature survey revealed that a good number of anthracene and substituted anthracences are potential lasing organic compounds. As per Mitsuo Maeda 9,10 dimethyl and 9,10 diphenyl anthracenes exhibit lasing properties around, 435-450nm. In continuation of our studies27 it was proposed to synthesize new lasing organic dyes in particular, new anthracene derivatives and study their photophysical properties besides the lasing characteristics. Search of literature indicate that 9,10 disubstituted anthracenes are well synthesized and reported. Hence we propose to synthesize 2,6 disubstituted anthracenes and 2,5 disubstituted anthracenes. In the first instance, it is proposed to synthesize 2,5 disubstituted anthraquinones which on reduction yield the target molecules (TM). 2,6- disubstituted or 2,5-disubstituted anthrancenes are our choice. Hence it is proposed to synthesize 2- Chloro, 5-nitro, 9,10-anthraquinone and to examine whether these type of molecules also exhibit lasing properties. Initially it is advisable to study the photophysical properties for better understanding of the lasing phenomena. The synthetic route for the sysnthesis of 2-Chloro, 5-nitro; 9-10-Anthraquinone is described below in scheme 1.
