Organophosphorus decorated lithium borate and phosphate salts with extended π-conjugated backbone

Several new bifunctional salts, Li[B(DPN) 2 ] , Li[B(DPN)(ox)] and Li[P(DPN) 3 ] , have been prepared from the phosphorus( v )-containing chelating ligand 2,3-dihydroxynaphthalene-1,4-(tetraethyl)bis(phosphonate) ( H 2 -DPN ). The new lithium salts were characterized by a variety of spectroscopic techniques. Both H 2 -DPN and Li[B(DPN) 2 ] have been structurally characterized by X-ray crystallographic methods. These salts are related to materials being examined for use in electrolyte solutions for lithium-ion battery (LIB) applications.
