Tóm tắt

AbstractA series of multi‐armed macrocycles with molecular weights up to 4400 Da was studied by desorption chemical ionization. Both negative‐ and positive‐ion spectra exhibited excellent signal‐to‐noise ratio, despite the limited amount of material sampled (0.1–1 pmol). The molecular ions generally represent the base peaks of the spectra, but the extent of fragmentation increases as the source temperature is raised.
