4,4'-sulfonyldibenzoic acid (H 2 SDBA) is a chemical compound . In the deprotonated state, it is a typical example of a semi-rigid V-shaped dicarboxylate ligand.
properties
Physical Properties
H 2 SDBA crystallizes in the monoclinic crystal system in the space group P 2 1 / m (space group no. 11) .
Chemical properties
If H 2 SDBA is deprotonated as SDBA 2− (SDBA for short), it is a versatile ligand for the construction of organometallic compounds, as it has six potential donor atoms that allow the formation of variable structures with different topologies and dimensions in different directions.
use
As a linker molecule, SDBA is used in the synthesis of new metal-organic framework compounds . For example, the MOF IITKGP-6 shows good water resistance and a high adsorption capacity for carbon dioxide , which makes it interesting for gas separation.
It can also be used for the synthesis of polymers.
safety instructions
When working with H 2 SDBA, respiratory protection must be worn to avoid inhaling fine dusts. Additional personal protective clothing such as nitrile gloves , gowns and protective goggles must also be worn.
