The transition metal complexes have been widely used in the research area of luminescent sensor, biological probe, electron and energy transfer, etc in recent decades because of their outstanding photophysical and electrochemical properties. Ru(II) polypyridyl complex has attracted more interest among these complexes. Ru(II) polypyridyl complex has become one of research hotspots in recent years due to its abundant ground state and excited state photophysics, appropriate excited lifetime, unique chemical stability, and rich redox properties. It is playing a key role in the development of photochemistry, photophysics, photocatalysis, NLO material, photo catalysis, electrochemistry, electron and energy transfer, ion recognition, and molecular recognition. The extensive research of Ru(II) polypyridyl complexes and their derivatives has promoted the development of the theory chemistry and applied chemistry. Ruthenium(II) pyridine complex has octahedral configuration with great plasticity of the molecular structure. Functional molecular devices can be designed through introducing various types of functional groups to the different positions of the ligand. They can play important role in the fields of solar water splitting, simulation of greenery, pH luminescent sensor, enzyme simulation, molecular recognition, and molecular catalysis. The paper is focused on the design and synthesis of novel polypyridyl ligands and corresponding Ru(II) complexes containing crown ether, or 4,5-diazafluorenone. The ion recognition, electron and energy transfer properties of these complexes have been studied through the measure of UV-Vis absorption, fluorescence, and electrochemistry.
