N1-((1H-Indazol-5-yl)methylene)-N2-(2-((2-((2-(((1H-indazol-6-yl)methylene)amino)ethyl)amino)ethyl)amino)ethyl)ethane-1,2-diamine

One novel molecular emissive probe L has been synthesized by classical Schiff-base reaction between 1H-indazole-6-carboxaldehyde and tetraethylenepentamine. The structure of compound L was confirmed by melting point, elemental analysis, ESI-MS spectrometry and by IR and 13C-NMR and 1H-NMR spectroscopy.
