The use of fastatombombardmentmassspectrometry is investigated as a technique to study a series of porphyrins (Hsub 2}P) and metalloporphyrins (MetP). Rates of demetalation and the redox chemistry of such compounds as well as complex inter- and intramolecular electron-transfer processes are examined. Comparison of the solution chemistry of metalloporphyrins with their behavior in FABMS lead to
使用快速原子轰击质谱作为研究一系列卟啉 (Hsub 2}P) 和金属卟啉 (MetP) 的技术进行了研究。检查了这些化合物的脱金属速率和氧化还原化学以及复杂的分子间和分子内电子转移过程。将金属卟啉的溶液化学与其在 FABMS 中的行为进行比较,可以了解发生在 FAB 基质中的物理化学事件的各个方面。通过使用具有不同电子或酸性性质的 FAB 基质,证明脱金属可以通过金属的质子置换或单电子还原发生。
