AI Article Synopsis
- A new supramolecular organic framework (SOF-7) was created using a solvothermal reaction between specific chemical compounds, resulting in a complex structure formed from both original and altered components.
- The framework features a unique three-dimensional structure with channels supported by hydrogen bonds and decorated with functional groups like cyano and amide.
- SOF-7 demonstrates impressive characteristics, including high thermal stability, resistance to solvents and moisture, and significant CO2 adsorption capacity, making it stand out among porous materials formed mainly through hydrogen bonding.
Article Abstract
A robust binary hydrogen-bonded supramolecular organic framework (SOF-7) has been synthesized by solvothermal reaction of 1,4-bis-(4-(3,5-dicyano-2,6-dipyridyl)dihydropyridyl)benzene (1) and 5,5'-bis-(azanediyl)-oxalyl-diisophthalic acid (2). Single crystal X-ray diffraction analysis shows that SOF-7 comprises 2 and 1,4-bis-(4-(3,5-dicyano-2,6-dipyridyl)pyridyl)benzene (3); the latter formed in situ from the oxidative dehydrogenation of 1. SOF-7 shows a three-dimensional four-fold interpenetrated structure with complementary O-H···N hydrogen bonds to form channels that are decorated with cyano and amide groups. SOF-7 exhibits excellent thermal stability and solvent and moisture durability as well as permanent porosity. The activated desolvated material SOF-7a shows high CO2 adsorption capacity and selectivity compared with other porous organic materials assembled solely through hydrogen bonding.
