Title

Supramolecular Polymer Formation Featuring Cooperative Halogen Bonding and Nonconventional sp2-CH···N Hydrogen Bonding

Abstract

The role of cooperative nonconventional hydrogen bonding and halogen bonding in the formation of supramolecular polymers is explored. In particular, the cocrystallization of 1-bromo-2,3,5,6-tetrafluorobenzene, or 1,2,4,5-tetrafluoro-3-iodobenzene, with each of the dipyridyls 4,4′-bipyridine, trans-1,2-bis(4-pyridyl)ethene, and 1,2-bis(4-pyridyl)ethyne results in the formation of linear supramolecular polymers in which the two components are held together by cooperative alternating nonconventional sp2-CH···N hydrogen bonds and halogen bonds.
