A thorough understanding of the interplay between the solid and liquid phases in hybrid solid-state electrolytes is crucial for optimizing their performance as battery electrolytes. This study investigates how interactions between different ionic liquid-based electrolytes and the metal-organic framework ZIF-8 influence the coordination and dynamics of Li⁺ in confinement. To this end, we examine five different ionic liquids, varying the chemical nature of the cation. Raman spectroscopy, supported by 2D solid-state NMR and simulations, are used to elucidate Li⁺ coordination and ion-wall interactions. The impact of these interactions on local Li⁺ dynamics and charge transport in the ionic liquid-ZIF-8 hybrid system is investigated using ⁷Li spin relaxation, impedance spectroscopy, and simulations. The results reveal a competitive interaction between Li⁺ and the ionic liquid cation with the ZIF-8 framework, which can be fine-tuned by modifying the molecular structure of the ionic liquid cation. As a consequence, local Li⁺ dynamics is enhanced, depending on the ionic liquid cation. The beneficial interactions in the confined system can even make Li⁺ the fastest diffusing species, in contrast to bulk electrolyte, where Li⁺ transport is limited by strong Li-anion clusters. Thus, blocking Li⁺-framework interactions through other competitive interactions might be an effective strategy to enhance Li⁺ dynamics and increase Li conductivity in a hybrid solid-state electrolyte. Although confinement within the ZIF-8 model system leads to an overall decrease in conductivity, this study provides valuable insights into the design of hybrid electrolytes for next-generation battery applications.</p>","PeriodicalId":60,"journal":{"name":"The Journal of Physical Chemistry B","volume":" ","pages":"6372-6384"},"PeriodicalIF":2.8,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144309307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, recent molecular dynamics simulations have uncovered previously unknown properties of Laurdan, revealing that it can adopt distinct conformations within the lipid bilayer, thereby influencing its molecular orientation. Despite these findings, experimental and quantitative validation has been lacking. Here, we present the first experimental study of the orientation of Laurdan in a phase-separated supported lipid bilayer, directly linking its spatial orientation to its emission spectra in liquid-ordered (L_o) and liquid-disordered (L_d) phases. Using azimuthally and radially polarized excitation beams, we show that in the L_o phase, Laurdan molecules align more parallel to the membrane normal, whereas in the L_d phase, they adopt a more planar orientation within the membrane. Interestingly, the emission spectra for both excitation modes converge at shorter wavelengths, but show deviations at longer wavelengths, particularly in the L_d phase. By refining our understanding of the behavior of Laurdan in lipid membranes, this study underlines the critical role of the molecular orientation of the dye in fluorescence-based membrane studies and highlights the need for orientation-sensitive analysis in biophysical investigations.</p>","PeriodicalId":60,"journal":{"name":"The Journal of Physical Chemistry B","volume":" ","pages":"6233-6240"},"PeriodicalIF":2.8,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144264863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
