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.
