摘要
采用XPS方法确定了平面双核酞菁钴分子中两个Co离子的价态.讨论了平面双核酞菁钴分子中Co离子的价态与分子构形、配位性质、分子识别和分子整流特性等之间的联系.在平面双核酞菁钴分子中,两个Co离子具有不同的价态,Co(Ⅰ)Pc-PcCo(Ⅲ)这种分子构形使得该分子表现出一些独特的性质.在配位化学上表现出一个Co(Ⅰ)Pc-PcCo(Ⅲ)分子与三个配体形成配合物.在形成单分子膜时表现出分子的识别能力,Co(Ⅰ)Pc-PcCo(Ⅲ)表现出分子整流特性.
In the present paper we confirm the valence of two Co ions in the planar (binuclear-Co-)phthalocyanine by using XPS method.We also discuss the correlation between the valence of two Co ions in the planar binuclear Co-phthalocyanine and molecular configuration,coordination property,molecular recognition and molecular rectifying character.In the molecules of the planar binuclear Co-phthalocyanine,the valences of two Co ions are different.The molecular configuration,Co(Ⅰ)Po-PcCo(Ⅲ),make this molecule display some (unique) properties.For example,one Co(Ⅰ)Pc-PcCo(Ⅲ)molecule can coordinate with three ligands to form complex.When forming single molecule membrance,the molecule displays the property of molecular recognition.In addition,the Co(Ⅰ)Pc-PcCo(Ⅲ)presents molecular rectifying character.
