Tetraarylborate polymer networks as single-ion conducting solid electrolytes.

ABSTRACT: A new family of solid polymer electrolytes based upon anionic tetrakis(phenyl)borate tetrahedral nodes and linear bis-alkyne linkers is reported. Sonogashira polymerizations using tetrakis(4-iodophenyl)borate, tetrakis(4-iodo-2,3,5,6-tetrafluorophenyl)borate and tetrakis(4-bromo-2,3,5,6-tetrafluorophenyl)borate delivered highly cross-linked polymer networks with both 1,4-diethynylbeznene and a tri(ethylene glycol) substituted derivative. Promising initial conductivity metrics have been observed, including high room temperature conductivities (up to 2.7 × 10^-4 S cm^-1), moderate activation energies (0.25-0.28 eV), and high lithium ion transport numbers (up to t_Li⁺ = 0.93). Initial investigations into the effects of important materials parame
