Protic Oligosilsesquioxane Dicationic Ionic Liquids with Two Types of Ionic Sites in Organic Frame
A method of synthesis of oligomeric siloxane protic ionic liquids capable of condensation reactions has been developed as starting compounds in the obtaining proton exchange membranes for fuel cells. Their organic frame is characterized by a combination of amine centers of different basicity (aliphatic and imidazole types) neutralized with ethanesulfonic acid and secondary hydroxyl groups. A change in the degree of neutralization of the amine centers significantly affects the structure of the compounds and the mechanism of proton migration. The conductivity of the obtained compounds reaches 9.8·10–4 S/cm at 100°C in the absence of moisture.
期刊介绍：
Theoretical and Experimental Chemistry is a journal for the rapid publication of research communications and reviews on modern problems of physical chemistry such as:
a) physicochemical bases, principles, and methods for creation of novel processes, compounds, and materials;
b) physicochemical principles of chemical process control, influence of external physical forces on chemical reactions;
c) physical nanochemistry, nanostructures and nanomaterials, functional nanomaterials, size-dependent properties of materials.
