摘　　要：本文合成了一种酞菁钴 (Ⅱ )化合物 ,研究了它在溶液中与咪唑形成轴向配合物的吸收光谱变化 ,并计算了配合物的组成及稳定常数 .用旋涂法制备了染料薄膜 ,通过配合物的吸收光谱与酞菁钴 (Ⅱ )的比较 ,光谱峰显著变窄 ,吸收峰红移 ,大大改善了染料的光学性质 .In this work, a phthalocyaninatocobalt(Ⅱ)(compound 1) and its imidazole complex were synthesied, the changes of absorption spectra of compound 1 upon addition of imidazole in solution were studied, and the equilibrium formation constant and the stiochiometry of the complex were calculated. The absorption spectrum of the complex is bathochromic-shifted and sharpened in compared with that of phthalocyaninatocobalt(Ⅱ) as a result the optical properties of the dye films is improved.\;
