Abstract Two novel functional rigid ligands, 2, 2′-and 4, 4′-bipyridyl-based “building blocks”, 9-ethyl-3, 6-bis [2-(4-pyridyl) ethenyl] carbazole (L 1) and 9-ethyl-3, 6-bis [2-(2- pyridyl) ethenyl] carbazole (L 2), were synthesized. Treatment of L 1, 2 as “building blocks” with Hg (SCN) 2 or HgI 2 afforded helixes, macrocycles, and chains, which can be further self-assembled by a π–π stacking interaction, hydrogen bond, and interatomic force in the ...
