【摘要】 合成了含有冠醚环化二硫烯的双核Au(Ⅰ)配合物[(3O-C2S4)Au2(PPh3)2](1),[(4O-C2S4)Au2.(PPh3)2](2),[(3O-C6S8)Au2(PPh3)2](3)和[(4O-C6S8)Au2(PPh3)2](4)以及富硫配合物[(btdt)Au2.(PPh3)2](5).通过X射线单晶衍射对配合物1～3和5进行了结构表征,并采用循环伏安法研究了配合物的氧化还原性质.研究结果表明,配合物4对Na+离子有明显的电化学响应,峰电位可以产生大约55 mV的正移动.更多还原

【Abstract】 A series of new Au(Ⅰ) complexes containing crown ether annelated dithiolate ligands,[(3O-C2S4)Au2(PPh3)2](1,3O-C2S2-4 =1,4,7-trioxa-10,13-dithiacyclopentadec-11-ene-11,12-dithiolate),[(4O-C2S4)Au2(PPh3)2](2,4O-C2S2-4=1,4,7,10-tetraoxa-13,16-dithiacyclooctadec-14-ene-14,15-dithiolate),[(3O-C6S8)Au2(PPh3)2][3,3O-C6S2-8 =2-{4,5-dithia-(3′,6′,9′-trioxaundecyl)-1,3-dithiol-2-yli-dene}-1,3-dithiol-4,5-dithiolate],and [(4O-C6S8)Au2(PPh3)2][4,4O-C6S2-8=2-{4,5-dithia-(3′,6′,9′,12′-tetr-aoxatetradecyl)-1,3-dithiol-2-ylidene}-1,3-dithiol-4,5-dithiolate],and the sulphur-rich dithiolate Au(Ⅰ) complex [(btdt)Au2(PPh3)2](5,btdt = benzotetrathiafulvalenedithiolate) were prepared and characterized.The crystal structures of complexes 1—3 and 5 were determined.Redox properties of these complexes were investigated by cyclic voltammetry and complex 4 shows significant response for Na+ ions with a large positive shift of ca.55 mV.更多还原
