| Summary: | 碩士 === 國立成功大學 === 化學系碩博士班 === 97 === A series of iridium complexes [Ir(��2-ppy)2(py′)Cl] was synthesized (Hppy = 2-phenylpyridine; py′ = 4-pyCOOH (5a), 3-pyCOOH (5b), 2-pyCOOH (5c), 4-pyCHO (5d), 4-pyCOOEt (5e), 3,4-py(COOEt)2 (5f), 3,5-py(COOEt)2 (5g), 4-pyCOO－PPN＋(5h), py (5i), 4-pyNH2 (5j), 4-pyOH (5k), 4-pyCMe3 (5l)). All complexes were characterized by EA, IR,NMR, UV-Vis and fluorescence spectroscopy. Seven single-crystal structures of complexes 5a, 5b, 5c, 5e, 5f, 5g and 5i were also determined.The chemical-sensing experiments indicate that complex 5a shows a better selectivity toward pyridine bases than other complexes.
