Abstract: | Five dimethylindium complexes of type Me2InL L = N-(4-methoxy)benzylidenethiobenzahydrazonato (1), N-(3,4-dimethoxy)benzylidenethiobenzahydrazonato (2), N-(4-N,N-dimethylamino)benzylidenethiobenzahydrazonato (3), N-(2-naphthyl)methylene thiobenzahydrazonato (4) and N-(9-anthryl)methylenethiobenzahydrazonato (5)] have been synthesized by reaction of trimethylindium with appropriate N-arylmethylenethiobenzahydrozones. The complexes obtained have been characterized by elemental analysis, 1H NMR, IR and mass spectroscopy. Compounds 1–5 emit blue colors at λmax = 432–479 nm when irradiated by UV light. The electroluminescent (EL) properties of 1–5 were examined by fabricating EL devices using 1–5 as emitter, respectively. The EL bands are located in the green region (513–578 nm). |
