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

ABSTRACT

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) (H2-DPN). The new lithium salts were characterized by a variety of spectroscopic techniques. Both H2-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.
