| Abstrakt: | Controlled assembly of two-dimensional (2D) supramolecular organic frameworks (SOFs) has been demonstrated through a binary strategy in which 1,4-bis-(4-(3,5-dicyano-2,6-dipyridyl)pyridyl)naphthalene ( 2 ), generated in situ by oxidative dehydrogenation of 1,4-bis-(4-(3,5-dicyano-2,6-dipyridyl)dihydropyridyl)naphthalene ( 1 ), is coupled in a 1:1 ratio with terphenyl-3,3',4,4'-tetracarboxylic acid ( 3 ; to form SOF-8 ), 5,5'-(anthracene-9,10-diyl)diisophthalic acid ( 4 ; to form SOF-9 ), or 5,5'-bis-(azanediyl)-oxalyl-diisophthalic acid ( 5 ; to form SOF-10 ). Complementary O-H···N hydrogen bonds assemble 2D 6 3 - hcb (honeycomb) subunits that pack as layers in SOF-8 to give a three-dimensional (3D) supramolecular network with parallel channels hosting guest DMF (DMF = N , N '-dimethylformamide) molecules. SOF-9 and SOF-10 feature supramolecular networks of 2D → 3D inclined polycatenation of similar hcb layers as those in SOF-8 . Although SOF-8 suffers framework collapse upon guest removal, the polycatenated frameworks of SOF-9 and SOF-10 exhibit excellent chemical and thermal stability, solvent/moisture durability, and permanent porosity. Moreover, their corresponding desolvated (activated) samples SOF-9a and SOF-10a display enhanced adsorption and selectivity for CO Competing Interests: The authors declare no competing financial interest. |
