Abstract: Matrix assisted laser desorption/ionization time of flight(MALDI-TOF) mass spectrometry was used for the mass spectrometry analyses of calixarene compounds. The influences of sample preparation, detection mode, laser intensity, voltage and time of delayed extraction on the measurement results were investigated. The mass spectrometry data of twenty-five compounds have shown the MALDI-TOFmass spectra with satisfactory performances in sensitivity, resolution and accuracy can be easily obtained. Anew mass spectrometry method was established and provided for the mass identification of calixarene compounds.

Key words: Matrix assisted laser desorption/ionization time of flight mass spectrometry, Calixarene, Structural characterization
