Description

Photo-responsive azobenzene-triazole systems will be designed to allow Z-selective anion binding, resulting in photo-reversible switchable anion availability and catalytic activity. Peptide functionali-zation will enable supramolecular aggregates, with anion binding constants depending on the available space for isomerization and thus on the aggregation state. As a route towards adaptive materials we envision to implement memory by modifying aggregate structures based on the steric requirement of the azotriazole E and Z forms during repeated photoisomerization cycles. The ultimate goal is to construct materials with memory-controlled photo-responsive anion binding properties.
