ABSTRACT: 

Two  new  Schiff  base  ligands  comprising  benzothiazole  derivatives,  namely 

(N,N',E,N,N'E)-N,N'-(1,3-phenylenebis(methanylylidene))bis(5-nitrobenzo[d]thiazoL2-amine 

(

L1

)  and  (N,N',E,N,N'E)-N,N'-(1,3-phenylene-bis(methanylylidene))bis(5-methylthiazo-L2-

amine  (

L2

),  have  been  synthesized  and  thoroughly  characterized  using  FTIR, 

1

H  NMR,  mass 

UV/vis  and  fluorescence  spectral  techniques.  Further,
