TP 5: Structure Reactivity Relationship with regard to Twin Polymerisation (1. FP)

The Mehring group studies structure-reactivity relationships in the Twin Polymerisation process. Variation of the ligands with respect to their electronic and steric properties and usage of several metals possessing different Lewis-acidities (group XIII, XIV und XV atoms) aiming the synthesis of novel Twin Monomer classes renders our concept. Especially, information about the influence of structural and electronic features of the novel Twin Monomers with respect to the polymerization process are accessible by these studies and shall be use in order to synthesis hybrid material exhibiting desired properties.

Within the first period of funding we have gained fundamental knowledge about structure-reactivity relationships in the Twin Polymerization process. For example, we have demonstrated that the choice of the ligands is crucial for the reactivity of the monomers and defines the properties of the final hybrid materials. Thus, electron density donating substituents at the ligands facilitate the polymerization process, whereas higher Lewis acidity of the metal centers leads to the formation of coordination polymers of the twin monomers. The latter is a crucial parameter for the capability of twin monomers to undergo Twin Polymerization.
