Abstract
A proton exchange solid support includes a porous polymer network including a polymer. The polymer includes a tetravalent boron-based acid group in a side chain of the polymer, and the tetravalent boron-based acid group includes a boron atom having a negative formal charge. A cation is ionically linked to the boron atom.
Claims11
A method of making a proton-exchange solid support, comprising:
- modifying a hydroxyl group of an acid group with a tetravalent boron-based acid group in a side chain of a polymer of a porous polymer network, wherein the tetravalent boron-based acid group comprises a boron atom covalently bonded to four atoms and having a negative formal charge;
- and
- ionically linking a cation to the boron atom.
