过渡金属4,4′,4″,4'''-四磺酸酞菁配合物的吸收光谱

INVESTIGATION OF THE ABSORPTION SPECTRA OF 4,4′,4″,4'''-TETRASULFONYL PHTHALOCYANINE COMPOUND OF TRANSITION METALS

报导了钼和第一过渡系列金属(Fe,Co,Ni,Cu,Zn)四磺酸酞菁配合物的吸收光谱。发现第一过渡系列Co,Ni,Cu,Zn四磺酸酞菁配合物在有机溶剂中的吸收光谱为单峰曲线(主峰),其极大值(λ_(max))有如下规律:Co~Ⅱ<Ni~Ⅱ<Cu~Ⅱ<Zn~Ⅱ,而第二过渡系列的钼四磺酸酞菁与前者不同,它与无金属四磺酸酞菁相似。还讨论了PH值对钼四磺酸酞菁的影响。

The electronic spectra of 4,4′, 4″, 4(?)= tetra sulfonyl phthalocyanine compounds of first series transition metals (Fe, Co, Ni, Cu, Zn) and second series transition metal (Mo) were measured. It was found that absorption bands of first series metals have single peak (main peak) and the band order (in λ_(max) value) of Co~Ⅱ<Ni^(Ⅲ) <Cu~Ⅱ<Zn~Ⅱ. The Mo differs from first series metals and is rather similar with metal-free tetrasulfonyl phthalocyanine. The effect of pH on the spectra of Mopompound has also been discussed.
