Rezumat:

Several azo derivatives containing both azulene and benzocrown ethers were investigated using mass spectroscopy-ESI method. The compounds form stable protonated molecular ions in positive method and deprotonated anions in negative method. The parent peaks were broken at higher energies and some general rules for their scission were evidenced.
