Molecular Architecture Effects on Bulk Nanostructure in Bis(Orthoborate) Ionic Liquids.

ABSTRACT: A series of 19 ionic liquids (ILs) based on phosphonium and imidazolium cations of varying alkyl-chain lengths with the orthoborate anions bis(oxalato)borate [BOB]^- , bis(mandelato)borate, [BMB]^- and bis(salicylato)borate, [BScB]^- , are synthesized and studied using small-angle neutron scattering (SANS). All measured systems display nanostructuring, with 1-methyl-3-n-alkyl imidazolium-orthoborates forming clearly bicontinuous L₃ spongelike phases when the alkyl chains are longer than C₆ (hexyl). L₃ phases are fitted using the Teubner and Strey model, and diffusely-nanostructured systems are primarily fitted using the Ornstein-Zernicke correlation length model. Strongly-nanostructured systems have a strong dependence on the c
