报导了八齿配体N,N，N′．N′四（2-苯并咪唑甲基）－1,4－H乙氨基乙二醚（EGTB）的4种从核钴（Ⅱ）配合物的合成及其红外（IR）、紫外可见（UV－Vis）光谱和电子自旋共振（ESR）谱表征．并用硝基蓝四氮唑（NBT）光照还原法证明这4种配合物均具有超氧化物歧化酶性质．与O_2反应的速率常数在10~6～10~7mol·L·s之间．
The octadentate ligands N, N, N ’are reported. Synthesis of 4 New Cobalt (Ⅱ) Complexes from N (Ⅳ) Tetrakis (2-Benzimidazolylmethyl) -1,4-H Ethoxyethanethylether (EGTB) and Their IR, UV -Vis) spectroscopy and electron spin resonance (ESR) spectroscopy. Nitroblue tetrazolium (NBT) photoluminescence method was used to prove that these four complexes have superoxide dismutase properties. The reaction rate constant with O 2 is between 10 ~ 6 ~ 10 ~ 7mol·L · s.
