Direct Synthesis of Poly(lithium organoborate)s and Their Ion Conductive Properties

Recent Advances in the Synthesis and Applications of Organoborane Polymers

“…For example, Ohno, Matsumi, and coworkers reacted lithium mesitylhydroborate with poly(ethylene oxide) (PEO) and then added different alcohols (ROH) to give polymers 60. The organoborate moieties in the main chain act as weakly coordinating counterions to lithium ions [148]. The combination of imidazolium ions and borate functionalities in the zwitterionic polymer 61 was found to be beneficial as it resulted in high conductivity despite a relatively high glass transition temperature [149].…”

Macrocyclic Weakly Coordinating Anions

“…[34] Matsumi et al synthesized nonporousp olyethers with tetracoordinated Bi nt he polymer chain ( Figure 3, upper left). [35][36][37] Recently Jäkle ad co-workers reported the synthesis of the first weakly coordinating block copolymers, which are nonporous ( Figure 3, upper right). [38] The most important weakly coordinating anionic polymer is probablyN afion, ap erfluorinated block copolymer with sulfonic acid groups (Figure 3, bottom).…”

Design and evaluation of imidazolium cation-based ionic liquids having double-armed anions for selective cation conduction

“…As anionic structure in electrolytes, borate anions such as tetrafluoroborate are frequently employed because of their reasonable stability and high ionic conductivity [12,13]. We have also reported several solid polymer electrolytes bearing dissociable borate salt structures [14][15][16]. Particularly, the polymer electrolyte bearing a pentafluorophenylborate showed markedly improved ionic conductivity.…”
