Abstract
A porous metal-organic framework (MOF) comprising metal ions coordinated to linkers, wherein one or more of the linkers has the following general formula wherein A is a heteroaryl or heterocycloalkyl ring or ring system selected from a 6-membered ring or a fused multi-ring system; wherein when A is a 6-membered ring the carboxylate side chains are in the 2,5 position; and n1 and n2 are independently integers selected from the range 0 to 20. Preferably, the MOF comprises two chemically-different linkers.
Claims29
A porous metal-organic framework comprising metal ions coordinated to linkers, wherein the linkers comprise:
- at least one first linker that has the following general formula:
- wherein A is a heteroaryl or heterocycloalkyl ring or ring system selected from a 6-membered ring or a fused multi-ring system;
- wherein, when A is a 6-membered ring, the carboxylate side chains are in the 2,5 position;
- and
- wherein n1 and n2 are integers independently selected from the range 0 to 20;
- and
- at least one second linker that has a different structure from the at least one first linker.

A method of synthesizing a porous metal-organic framework, the method comprising:
- (a) dissolving metal ions and plural chemically different linkers in water to form a mixture, wherein one or more of the linkers has the following general formula:
- wherein A is a heteroaryl or heterocycloalkyl ring or ring system selected from a 6-membered ring or a fused multi-ring system;
- wherein when A is a 6-membered ring the carboxylate side chains are in the 2,5 position;
- and
- wherein n1 and n2 are integers independently selected from the range 0 to 20;
- (b) adding a Brønsted-Lowry base to the mixture;
- and
- (c) heating the mixture to produce a crystalline material.
