硫代多联吡啶铂(II)配合物的合成、性质及在光催化制氢中的应用

Abstract

Two new ligands 4-(p-thioacetic-S-methylphenyl)-6-phenyl-2,2'-bipyridine[(HCNNPh)-N-boolean AND-N-boolean AND center dot(CH2SCOCH3), L3] and 6- (p-thioacetic-S-methylphenyl) -2,2'-bipyridine [(HCNN)-N-boolean AND-N-boolean AND (CH2SCOCH3), L5] as well as their platinum(II) complexes (ClPtCNN)-N-boolean AND-N-boolean AND(PhCH2SCOCH3) (C3) and (ClPtCNN)-N-boolean AND-N-boolean AND center dot (CH2SCOCH3) (CS) were synthesized and characterized by H-1 nuclear magnetic resonance (H-1 NMR), electrospray ionization mass spectra(ESI-MS) and X-ray diffraction(XRD) analysis. Photophysical and electrochemical properties of the complexes were studied based on the UV-Vis absorption and emission spectra, excited-state lifetime measurements. It was found that photogenerated hydrogen efficiencies of [(ClPtCNN)-N-boolean AND-N-boolean AND(CH3) (PhCH3)] (C1), [(ClPtCNN)-N-boolean AND-N-boolean AND(PhCH3)] (C2), C3, [(ClPtCNN)-N-boolean AND-N-boolean AND(CH3)] (C4) and C5 are in accordance with their emission lifetimes, and are arranged in the order C4>C1>C5>C2>C3.
