Abstract (English)

The first part of the present work describes the synthesis, characterization and the

photochemical behaviour of new comb-like polymers bearing chalcone (1,3-

diphenyl-2-propen-1-one) groups in the side chains. The photochemical analysis of

these polymers showed that homopolymers, in which the chalcone group is directly

attached to the main chain, showing only the E/Z-isomerization during the irradiation

with UV-light; while building in MMA-units in the chain, retardet the reaction. Building

in different spacers between the main chain and the chalcone group, causes the

polymers with 5- respectively 7 CH₂-units to be done during the irradiation

a E/Z-isomerization and a [2+2]-photocycloaddition.

Further could the synthesis of a polyrotaxan with radical polymerization be

realized. The prove of the existence of the complex would be realized with the help

of NMR-spectroscopy and FAB-measurement. The comparison of the complex with a

model compound showed prominent signal shifts, different solutionsattributs and a

differenciated thermical behaviour, too. The photochemical analysis demonstated

also that the complex did only the isomerization during the irradiation with UV-light,

while the model compound showed beside also a crosslinking reaction.

The radical polymerisation of methacrylmonomers, which included the 3-(9-

anthracenyl)-1-phenyl-2-propen-1-one group, could not be realized. This group

inhibited in a still unknown way any chainstarting and so the polymerization.

The second part of the work is occupied in the enzymic polymerization of

aminochalcons with HRP/H₂O₂. It could be shown, that proper aminochalcones,

according to the period of reaction, react to oligomeres, polymers and insoluble

products. These products are seen as thermicalstable polymers until ca. 300 °C.
