| Summary: | 碩士 === 國立臺北科技大學 === 有機高分子研究所 === 105 === Square planar platinum complexes have attracted much attention as fluorescence materials. The research is quite popular in recent years. Structure and photophysical properties of platinum metal complexes is interesting for our laboratory.
We successfully synthesize a series of short fluoro-ponytailed pyridine ligand[3-RfCH2OCH2-pyridine, Rf = CF3, CF2CF2H, CF2CF2Cl, CF2CF3]. we can react 3-RfCH2OCH2-pyridine[Rf = CF3, CF2CF2H, CF2CF2Cl, CF2CF3] with platinum dihalide [chloride, bromide, iodide] to generate the trans-form platinum complexes{[trans-(3-RfCH2OCH2-pyridine)2PtX2], Rf = CF3, CF2CF2H, CF2CF2Cl, CF2CF3, X = Cl, Br, I} and cis-form platinum complex[cis-(3-HCF2CF2CH2OCH2-pyridine)2PtCl2]. The characteristics of new compounds we synthesize were measured by NMR, FT-IR, GC-MS and FAB-MS.
The trans-form platinum complexes{[trans-(3-RfCH2OCH2-pyridine)2PtX2], Rf = CF3, CF2CF2H, CF2CF2Cl, CF2CF3, X = Cl, Br, I} is compared with trans-dichloro(dipyridine)platinum(II), trans-dichloro[di(3-methylpyridine)platinum(II)], thr trans-form platinum complexes is better at quantum yield and lifetime. The compounds have fluoro-ponytailed, so it has good stability in the air with the water.
The trans-form platinum complexes{[trans-(3-RfCH2OCH2-pyridine)2PtX2], Rf = CF3, CF2CF2H, CF2CF2Cl, CF2CF3, X = Cl, Br, I} will be stimuli-responsive materials test. We found that it was influenced by thermal, mechanical forces and solvent. The packing sttuctures in the solid state and the photophysical is change. The stimuli-responsive materials we were measured by PL, FT-IR and PXRD.
