a Chemical structures of the molecular ligands 1 [1,4-bis(4-pyridyl)-benzene], 2 [4,4″-dicyano-1,1′:3′,1″-terphenyl], 3 [1,4-bis(4-pyridyl)-biphenyl], and 4 [1,3-bis(4-pyridyl)-benzene] employed in this work. b Schematic illustration of the coordination motifs achieved in this work. The angles between the ligands approaching to the same Ce atom are marked by α.
