Hydrogen bonds between polyphenol (p-HOC6H4O)6W and bipyridines: (4,4′-bipy·HOC6H4O)6W and 3-D networks [{4,4′-(NC5H4)2(CH2 CH2)}n{(HOC6H 4O)6W}]∞ (n = 2, 3)
Abstract
Polyphenol (p-HOC6H4O)6W is stable with respect to condensation, and formed (4,4′-bipy·HOC6H4O)6W and the 3-D networks [{4,4′-(NC5H4)2(CH2 CH2)}n{(HOC6H 4- O)6W}]∞ (n = 2, 3), when treated with 4,4′-bipy and 1,2-di-4-pyridylethane, respectively.
