External control of multivalent interactions (A03)

• Subject Area: Preparatory and Physical Chemistry of Polymers ; Organic Molecular Chemistry - Synthesis and Characterisation
• Term: from 2008 to 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 32049920

In this project functional host-guest systems will developed by exploiting multivalent and cooperative effects in combination with photoswitchable non-covalent interactions. Thus light will be used to externally control the supramolecular polymerization of multivalent porphyrin and phthalocyanine building blocks on the one hand and to actively move multivalent constructs over surfaces on the other hand. By multiplying the photoswitchable supramolecular units in multivalent architectures dynamic association and dissociation processes will be amplified to the mesoscopic length scale of the light used.
