Abstract
A covalently linked organic network includes a plurality of boron-containing clusters linked together by a plurality of linking groups. The covalently linked organic networks are characterized by having each linking group bonded to at least two distinct boron-containing clusters.
Claims12
A covalently linked organic network comprising:
- a plurality of boron-containing clusters having the following formula:
- a plurality of linking groups that link the boron-containing clusters together, each linking group bonded to at least two distinct boron-containing clusters, the plurality of linking groups include a linking group described by Formula V-X:
- wherein:
- R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, R14, R15, and R16 are each independently H, alkyl, OH, alkoxy, sulfur-containing groups, silicon-containing groups, halogen, nitro, amino, cyano, boron-containing groups, phosphorus-containing groups, carboxylic acids, or esters and T is a tetrahedral atom or a tetrahedral group or cluster;
- A1, A2, A3, A4, A5, and A6 are each independently absent or any atom or group capable of forming a sable ring structure;
- and
- wherein the plurality of boron-containing clusters and the plurality of linking groups are arranged to form either a covalently linked organic framework or a covalently linked organic polyhedron.

A covalently linked organic network comprising:
- a plurality of boron-containing clusters having the following formula
- a plurality of linking groups that link the boron-containing clusters together, each linking group bonded to at least two distinct members of the plurality of boron-containing clusters the moiety described by Formula I, wherein the linking groups include a component selected from the group consisting of:
- wherein:
- R1 through R12 are each independently H, alkyl, OH, alkoxy, sulfur-containing groups, (e.g., thioalkoxy), silicon-containing groups, halogen, nitro, amino, cyano, boron-containing groups, phosphorus-containing groups, carboxylic acids, or esters
- R20, R21, R22, R23, R24, and R25 are each independently H, alkyl, OH, alkoxy, sulfur-containing groups (e.g., thioalkoxy), silicon-containing groups, halogen, nitro, amino, cyano, boron-containing groups, phosphorus-containing groups, carboxylic acids, esters, or a bond to a member from the plurality boron containing cluster with the provisio that formula XV at least two groups of R20 to R25 are bonds to two distinct members of the plurality of boron containing clusters and for formula XVI at least two groups of R20 to R29 are bonds to two distinct members of the plurality of boron containing clusters:
- and
- n is an integer greater than or equal to 1.
