We present a new templating approach that combines the templating properties of nanoporous networks with the dynamic properties and the lattice mismatch of domain boundaries. This templating approach allows for the inclusion of guests with different sizes without the need for a strict molecular design to tailor the nanoporous network. With this approach, nonperiodic patterns of functional molecules can be formed and studied. We show that domain boundaries in a trimesic acid network are preferred over pores within the network as adsorption sites for fullerenes by a factor of 100 200. Pristine fullerenes of different sizes and functionalized fullernes were templated in this way.
