Graphical Abstract

Nanocolander: Sub-nanometer thin organic materials with uniform imprinted pores are formed by controlled polymerization within temporary self-assembled scaffolds. Pores are measured by a colored size-probe retention assay. A nanocapsule with no pores retains yellow, red, and blue probes and is colored brown; 0.8 nm pores lead to release of yellow probes, while capsules with 1.3 nm pores only retain blue probes.
