Abstract

The Dielsโ€Alder addition polymerization of bispyrone 1 with 2 mol bismaleimide 2 was shown to lead to cyclic polyimides 3 (64%, Mฬ„~n~ = 15 000 g/mol) and to cyclic oligomers (36%) applying by gelโ€permeation chromatography analysis (GPC) and by means of matrixโ€assisted laser desorption/ionisation technique (MALDI).

Hexatriacontane (C 36 ) was exposed to vacuum ultraviolet radiation. The formation of double bonds was investigated by derivatization, i.e. these olefinic structures were transformed by epoxidation in order to determine their number in the molecule. The extent of the reaction was determined by means

Ultraviolet matrix-assisted laser desorption can be used to enhance formation of [M + HI+, [M + Na]+, and [M + K]+ ions from small peptides for Fourier transform mass spectrometry (RIMS). In accord with laser desorption (LD) time-of-Right experiments, matrices such as nicotinic acid and 2-pyrazineca

Matrix-assisted laser desorption/ionization combined with time-of-ร‘ight mass spectrometry (MALDI/TOF-MS) was used for the analysis of low molecular mass compounds. Three classes of molecules were studied : organic acids, salts of oxyanions and amine-based chelating compounds. Mass spectra from sampl
