Abstract
Porous networks are described linked by boronates. Also described are processes for producing the porous networks. The porous networks are formed by reacting a polyboronic acid with itself or with a polydiol, a polydiamine, or a polyamino alcohol. The resulting boronate linkage is covalently bonded. The characteristics and properties of the resulting porous material can be varied and altered by changing the reactants and by incorporating functional groups into the reactants. Of particular advantage, the porous materials can be formed at or near atmospheric pressure and at low temperature in the presence of one or more solvents.

A process for forming a boronate linked porous network comprising:
- reacting a polyboronic acid or an acyclic boronate ester thereof with a polydiol, a polyamino alcohol, or a polydiamine to form a covalently bonded polymeric or oligomeric porous network linked via boronate linkages, wherein the reaction occurs at or near atmospheric pressure in the presence of a first solvent and a second solvent, the first solvent comprising an alcohol, the second solvent having a boiling point less than about 110° C., and wherein the reaction occurs at a temperature from about 15° C. to about 110° C.
A process for forming a boronate linked porous network comprising:
- reacting a polyboronic acid or an acyclic boronate ester thereof with a polyamino alcohol or a polydiamine to form a covalently bonded polymeric or oligomeric porous network linked via boronate linkages, wherein the reaction occurs at or near atmospheric pressure, and wherein the reaction occurs at a temperature from about 15° C. to about 110° C.
