This study investigates solute–solvent interactions in ternary systems consisting of lithium trifluoromethanesulfonate (LiOTf) as the solute and tetraethylene glycol dimethyl ether (TEGDME) 1,2-dimethoxyethane (DME) solvents over a range temperatures (293.15–313.15 K). A multidisciplinary approach involving computational modeling, thermodynamic analysis, acoustic measurements was used to elucidate molecular-level dynamics. The positive Vϕ0 values analysis revealed prevalence investigated (LiOTf + H2O DME/TEGDME) solutions. Hepler's constant determined predict structure maker/breaker behavior. Cyclic voltammetry showed that TEGDME offers higher electrochemical window (EW) 1.36 V 0.01 1.40 0.05 compared with 1.25 DME 1.38 DME, yielding favorable comparable working EWs. DFT calculations using B3LYP functional 6-311++G(d,p) basis set provided insights into electron-donating -accepting properties molecules, showing reactivity for LiOTf. These findings present novel electrolyte systems, which hold potential applications energy storage technologies.

Exploring ionogels with superior conductivity, mechanical properties, and long-lasting room temperature phosphorescence (RTP) offers considerable potential for new-generation optoelectronics. However, reports on remain limited owing to the contradiction between flexibility required stretching rigidity necessary RTP load-bearing within same ionogels. Here, a facile strategy is reported enhance toughness extend of by salting-out-induced microphase separation, which results in formation an IL-rich phase (soft) ionic conduction polymer-rich (stiff) energy dissipation clustering-triggered phosphorescence. The obtained exhibit high stretchability (≈400% strain), (≈∼20 MJ m
