The thermodynamics and kinetics of binding of CO 2 , CO, and H + to N-racemic and N-meso stereoisomers of the cobalt (I) macrocycle CoL + (L=5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene) have been determined in aqueous media with use of the pulse radiolysis technique and transient ultraviolet-visible spectroscopy. N-rac- or N-meso-CoL + was produced by the hydrated electron
CO 2 、CO 和 H + 与钴 (I) 大环 CoL + 的 N-外消旋和 N-内消旋立体异构体结合的热力学和动力学(L=5,7,7,12,14,14-六甲基- 1,4,8,11-四氮杂环十四-4,11-二烯)已在水性介质中使用脉冲辐射分解技术和瞬态紫外-可见光谱法测定。N-rac- 或 N-meso-CoL + 是通过 N-rac- 或 N-meso-CoL 2+ 的水合电子还原产生的,通常添加叔丁醇以清除羟基自由基
