A building BLOCK approach to bis-porphyrin cavity systems with convergent and divergent wall orientations

Porphyrin containing molecular building blocks have been linked together using s-tetrazine or 1,3-dipolar coupling protocols to yield bis-porphyrin cavities of defined shape and size which were evaluated by molecular modelling.
