【摘要】 以有机分子自由基4H,4’H-2,2’-双色烯-4,4’二酮(以下简称BCDO)为配体,在混合溶剂氯仿-乙醇存在下,加入一定物质的量的CoCl2·6H2O,加热回流一定时间,通过配位反应成功得到新型的BCDO-Co(Ⅱ)配合物.所得配合物利用1H-NMR、IR、HR-MS对其结构进行了表征,结果表明配体中的烯醇羟基氧和醚氧原子与金属离子相互作用,使得BCDO与Co2+按照摩尔比1∶2配位,推测了所得BCDO-Co(Ⅱ)配合物的可能结构,同时对配合物的紫外吸收光谱和荧光性能进行了测定.更多还原

【Abstract】 A new complex of BCDO-Co( Ⅱ)( BCDO = 4H,4’H-2,2’-bichromene-4,4’-dione) was synthesized from the reaction of CoCl2·6H2O and BCDO in chloroform-ethanol under reflux. The synthesized product was characterized by means of1H-NMR,IR and HR-MS. The IR spectra indicated that the oxygen atom of enolic hydroxyl group and the ethereal oxygen atom in BCDO could bind to Co2 +and form complex BCDO-Co( Ⅱ),and HR-MS showed that the molar ratio of BCDO to Co2 +was 1∶2 when coordinated. The probable structure of complex BCDO-Co( Ⅱ) was determined by experimental facts,and the ultraviolet absorption speetra and fluorescence property of complex BCDO-Co( Ⅱ) were tested.更多还原
