Abstract

A family of pyridyl-functionalized arylacetylene C-H hydrogen bonding (HB) receptors were synthesized and binding interactions to perrhenate (ReO4-) studied in the solid state. The protonation and alkylation state of the pyridine nitrogen dictate the location and denticity of the interactions. X-ray structures of neutral 1 and singly charged 2a+·ReO4- reveal the formation of favorable self-complementary dimers, owing to the presence of nitrogen HB acceptor sites. Dismissal of these dimers upon elimination of nitrogen HB acceptors on the receptor result in an array of multidentate C-H HB receptor-guest contacts.
