Chapter One describes the general principles of luminescent cyclometallated complexes of transition metal ions. A brief introduction about spectroscopic properties of lanthanides and sensitisation of their luminescence is provided. Examples of previous research by Ward group and from other groups into cyanide-bridged d-f complexes and Ir/Ln bimetallic complexes are described. Chapter Two describes the synthesis of bis(phenylpyridine) iridium(III) dicyanide complexes and the used of these complexes as the basis of cyanide-bridged polynuclear assemblies, in both coordination networks with lanthanide(III) cations and, discrete molecular species by bridging to {Re(phen)(CO)3t units. The structural and photophysical behaviour of these complexes have been performed. Chapter Three describes the structure of the anionic complex [Ir(ppy)2(CN)2r and its solvent environment in water have been studied by DFT calculations, in order to get further information on the specific solvent-solute interaction governed by the hydrogen bond in the solvation hydration shell. Chapter Four describes the preparation of a series of luminescent complexes based on {Ir(F2ppy)2} [F2Ppy = cyclometallating anion of 2-(2',4'-difluorophenyl)pyridine] units, with two pyrazolyl-pyridine units, separated with spacer groups butyl (CH2)4, methoxyphenyl and benzophenone, of which first N,N-chelating terminus was coordinated to Ir(III) and the second was bound to Ln(III). The photophysical properties of the Ir/Ln dyads have been investigated in solution. 2013 thesis https://ir.upsi.edu.my/detailsg.php?det=1133 https://ir.upsi.edu.my/detailsg.php?det=1133 text eng N/A openAccess Doctoral Universiti Pendidikan Sultan Idris Fakulti Sains dan Matematik N/A |
