N1-Benzylidene-N2-(2-((2-((2-(benzylideneamino)ethyl)amino) ethyl)amino)ethyl)ethane-1,2-diamine

A tetraethylene pentamine-diamine ( L4), the biggest compound in the family of dibenzylated diimine -polyamines ( L1– L4) has been synthesized by classical Schiff-base reaction between benzaldehyde and the diamine tetraethylenepentamine, and the structure was confirmed by elemental analysis, ESI-MS spectrometry and by IR and 1H-NMR spectroscopy.
