polymer, which is constructed from unsymmetrical dinuclear
lanthanidebuilding blocks. Thecoordinationpolymerpossess
helical chain structure that is further interlinked to the neigh-
boring coordination polymers based on hydrogen bonding
interactions, which results into a 2D architecture. The new
benzimidazole anchored benzoate complex of Tb3þ exhibits
bright green luminescence efficiency in the solid state with a
quantum yield of 15%, thus rendering it as promising candi-
date for use in various photonic applications. By contrast, the
poor sensitization observed for the corresponding Eu3þ com-
plex is mainly due to the larger energy gap between the ligand
