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 (L1) and 9-ethyl-3,6-bis[2-(2-pyridyl)ethenyl]carbazole (L2), were synthesized. Treatment of L1,2 as “building blocks” with Hg(SCN)2 or HgI2 afforded helixes, macrocycles, and chains, which can be further self-assembled by a π–π stacking interaction, hydrogen bond, and interatomic force in the solid state to form two-dimensional networks. In complexes 1–4, HgII centers all adopt four-coordination modes in different coordination environments, but they present different architectures with slightly adjusted structures of the ligands and counteranions, indicating that the nature of the ligand and anion plays an important role in the coordination networks. The luminescent properties of compounds 1–4 have been studied.(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
