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.
Claims9
A boronate linked porous network comprising:
- a boronate comprising the reaction product of 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, the boronate linked network having a pore size of less than about 200 angstroms.
A process for forming a boroxine linked porous network comprising:
- a dehydration product formed by reacting a polyboronic acid with itself to form an anhydride porous network, the porous network defining pores having a pore diameter of less than about 200 angstroms.
A boronate linked porous network comprising:
- a boronate comprising the reaction product of a polyboronic acid or an acyclic boronate ester thereof with a polydiol to form a covalently bonded polymeric or oligomeric porous network, the boronate linked network having a pore size of less than about 200 angstroms.
