| 中文摘要 | matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (maldi-tofms) was used to study a series of synthetic cationic porphyrins as the perchlorate and bromide salts. this work presents the analytical results for the porphyrins obtained using 2,5-dihydroxybenzoic acid (dhb) and 1,8,9-anthratriol as matrices. the selective use of matrix affects ion formation from these porphyrins. by using dhb as the matrix, we not only observed [m - ncio(4)](+) (n = 1-4) ions, but also obtained [2m - ncio(4)](+) (n = 2-7) ions from the synthetic cationic porphyrins. the space volume of the side chains (r groups) and the nature of the anions (br- or cio4-) affected the relative importance of monomeric and dimeric ions of the porphyrin. the possible mechanisms of desorption and ionization of these cationic porphyrins were also considered in this study. maldi-tofms proved to be a very useful method for obtaining structural information on these synthetic cationic porphyrins. copyright (c) 1999 john whey & sons, ltd. |
