Xray crystallographic investigations on acridinedione schiff base derivatives and organic phosphate salts

Abstract

Acridine C13H9N is a planar heterocyclic aromatic molecule newlinederived from anthracene by the replacement of one meso CH group by newlinenitrogen Acridinediones the acridine derivatives having two keto functional newlinegroups at the 1st and 8th positions are found to be good antimalarial agents newlineAcridine18diones were also found to give fluorescence and laser activities around newline480 nm and their fluorescence quantum yield and laser efficiency could be newlinealtered by changing the substituents at the 9position and on the nitrogen newlinecentre newlineSchiff bases are the condensation product of aldehyde or ketone newlinewith the primary amine which leads to the displacement of CO group by newlineCNR group Schiff bases of salicylaldehyde with amines anils show the newlinephenomena of solid state photochromism and thermochromism newlineDehydroacetic acid another Schiff base is a pyrone derivative used as a newlinefungicide and bactericide newline newline
