Abstract Triazolium-based ion-conductive nanoparticles (NPs) with cross-linked cores were synthesized using a self-assembled block copolymer comprising N -vinyl-4-ethyl-1,2,4-triazolium bis(trifluoromethanesulfonyl)imide (NVETri-NTf 2 ) and N -vinyl-1,2,4-triazole (NVTri) and site-selective cross-linking quaternization in a selective solvent. Four different dihalide compounds, namely diiodoethane, diiodooctane, dibromoethane, and dibromooctane, afforded four core-shell NPs NP(C2-I), NP(C8-I), NP(C2-Br), and NP(C8-Br), respectively. DLS analyses demonstrated the formation of stable NPs with uniform sizes (mean diameter = 192 nm for NP(C2-I), 196 nm for NP(C8-I), and 195 nm for NP(C2-Br)). Among these, NP(C2-Br) exhibited the highest ionic conductivities. In the presence of 30 wt% ionic liquid, high ionic conductivities of 1.26 × 10 −3 , 3.31 × 10 −4 , and 1.36 × 10 −4 S/cm were achieved with solid-state NP(C2-Br) at 90, 55, and 25 °C, respectively, which are due to the enhanced segmental molecular motion and the formation of a preferable ionic-conductive path composed of the hydrophobic ionic-liquid based shell with the added ionic liquid.
