## Abstract The DielsโAlder 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 gelโpermeation chromatography analysis (GPC) and by means of matrixโassisted laser desorption/i

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
We present a new target modification for commercial ion sources to facilitate the use of liquid matrices such as glycerol and lactic acid in infrared matrix-assisted laser desorption/ionization (IR-MALDI). Benefits of this modification include increased sensitivity compared with the unmodified comme
