Novel ruthenium(II)bpy complexes of the phenanthrimidazole-pendant cyclen and cyclam macrocyclic ligands were synthesized as inorganic host molecules.Inorganic host design was planned as a "complex ligand" form because of its tetraaza macrocyclic unit, which has the ability to coordinate to the metals.Photophysical properties and metal selectivity of inorganic hosts RuL1A and RuL2 complex ligands were investigated by UV-vis and fluorescence spectros-
