Ruthenium Polypyridyl Complexes

The syntheses and characterisation of a series of mononuclear and dinuclear ruthenium polypyridyl complexes based on the bridging ligands 1,3-bis-[5-(2-pyridyl)-1H-1,2,4-triazol-3-yl]benzene, 1,4-bis-[5-(2-pyridyl)-1H-1,2,4-triazol-3-yl]benzene, 2,5-bis-[5-(2-pyridyl)-1H-1,2,4-triazol-3-yl]thiophene, 2,5-bis-[5-pyrazinyl-1H-1,2,4-triazol-3-yl]thiophene are reported. Electrochemical studies indicate that in these systems, the ground state interaction is critically dependent on the nature of the bridging ligand and its protonation state, with strong and weak interactions being observed for thiophene- and phenylene-bridged complexes, respectively.

Quantum dots (QDs) have shown promising potential to many biomedical and biological applications, mainly in drug delivery or activation and cellular imaging. These semiconductor nanoparticles, QDs, whose particle size is in the range of 2-10 nanometer with unique photo-chemical and -physical properties that are not possessed by any other isolated molecules, have become one of the distinct class of imaging probes and worldwide platforms for manufacturing of multifunctional nanodevices. In this chapter, properties, applications of QDs, and importance in the biomedical field especially in drug delivery is presented.
