Synthesis Characterization and Applications of Some Transition Metal Complexes with Heterocyclic Ligands

Abstract

1,8-Naphthyridine(Nap) compounds have been extensively investigated not only due totheir special conjugate and#61552;and#61472;electronic structures, good coordination capabilities, favorable photo newlinephysical and photochemical properties but also because of their potential applications as functional materials in the fields of solar energy conversion, sensors, supramolecular assemblies, photo catalysis, nonlinear optical materials, biological activities and optical molecular devices etc. A number of 1,8-naphthyridine derivatives have been synthesized since the first 1,8- naphthyridine compound was prepared in the 1920 s. 1,8 Naphthyridine (Nap) serves as a versatile ligand in coordination chemistry because it adopts various coordination modes such as newlinemonodentate, bidentate and bridging, and the ligand often gives novel transition-metal complexes. Numerous complexes with naphthyridine-based ligands in different coordination newlinemodes have also been reported since 1969. newline
