A new cross-linkable ionic group-functionalized ladder-like structured polysilsesquioxane was utilized as crosslinker for fabrication of hybrid ionogels. The ionic ladder-like polysilsesquioxane was completely solution processable in ionic liquid electrolytes and through chemical crosslinking, hybrid ionogel electrolytes with high ionic conductivity and electrochemical stability were obtained. Lithium ion batteries assembled with these hybrid ionogels electrolytes exhibited excellent cell cycling performance at elevated temperatures, suggesting the highly utile nature of our hybrid ionogel electrolytes.

Herein, we demonstrate a successful preparation method of ionic liquid functionalized POSS hybrids by quaternization of imidazole salt with Octa-(?-chloropropyl) POSS. A novel photofunctional hybrid soft material POSS- min-[Eu(tta)4] (tta:2-thenoyltrifluoroacetone) was reported via an ion-exchange reaction between imidazolium-based POSS(POSS-min-Cl) and lanthanide complex [Eu(tta)4]-. The obtained hybrids were extensively characterized by FT-IR, 1HNMR, 13CNMR, UV–Vis, PL and TGA in detail. What's more, POSS-min-[Eu(tta)4] displays higher fluorescence intensity, longer lifetime and higher thermostability than corresponding pure complex. More significantly, POSS-min-[Eu(tta)4] exhibits the improvement of photo physical properties (? = 53.73 %) and is selected as the representative sample to examine the potential fluorescence sensing of metal cations. The hybrid POSS-min-[Eu(tta)4] has selective fluorescent quenching effect for different metal ions, especially for Cu2+. These results provide meaningful data for the multi-component assembly and responsive luminescent of photo functional hybrids based on modified ionic liquid and lanthanide, which can be expected to have potential application in organic light-emitting devices(OLED) or sensor.
