用分光光度法研究了一种新的尾式卟啉钴——间-[邻-(4-二乙胺基丁酰氨基)苯基]三苯基卟啉合钴(Ⅱ)[缩写为meso-MDBPTPP Co(Ⅱ)]与含N有机碱(咪唑,吡啶,脂肪胺等)的加合作用,测定了这些有机碱同卟啉钴的加合平衡常数。实验结果表明:原来是五配位的尾式钴卟啉与含N有机碱可一步形成1:1的加合物,从而生成六配位的配合物;同时发现伯胺类的平衡常数与BH~+的酸常数K_a之间的关系式为:lgK=3.82pK_a+9.58 A new cobalt (Ⅱ) complex of tailed porphyrin cobalt-m- [o- (4-diethylamino butyrylamino) phenyl] triphenylporphyrin [abbreviated as meso -MDBPTPP Co (Ⅱ)] with N-containing organic bases (imidazole, pyridine, aliphatic amines, etc.), the addition equilibrium constants of these organic bases with cobalt porphyrin were determined. The experimental results show that: the original five-coordinated tail cobalt porphyrins and N-containing organic base can form a 1: 1 adduct step, resulting in six coordination complexes; also found that the primary amine equilibrium constant BH ~ + Acid constant K_a the relationship between the formula: lgK = 3.82pK_a + 9.58
