Synthesis and characterization of some new azo-schiff bases as energy rich candidate compounds derived from 1, 5-diaminoanthraquinone by fusion method

الملخص EN

This work, which can be considered as a complement to our previous studies concerning chemical energy storage systems developing programmed, proposes the synthesis of new azo-Schiff bases derived from 1, 5-diaminoanthraquinone (DAAQ) resulting in an improvement in their orption spectra.

Five new derivatives (An1-An5) were synthesized by gentle fusing of (1 mmol of DAAQ) with (2 mmol) of early prepared azo derivatives of 2-hydroxy benzaldyhde.

Medium to good yield was recorded on applying this method.

Microwave irradiation of the same mixtures led to decomposition of the starting azo materials whereas prolonged reflux in DMSO was unproductive.
