Block polymer structure‐directing agents (SDA) enable the production of porous nanoscale materials by controlling the arrangement of material precursors. The subsequent removal of the polymer thus yields porous nanomaterials that are useful for a wide range of applications including energy storage and catalysis. The iteration of most such strategies however leads to complex sequences of nanomaterials that change multiple spatial variables at a time, including morphology, pore size, and wall thickness. In contrast, persistent micelle templates (PMT) are based upon the kinetic entrapment of polymer chains to enable sample adjustments with constant morphology (isomorphic) and constant pore size (ref.1). Such series of nanomaterials with a single spatial variable are well poised to clarify cause-and-effect for nanoscale phenomena. The PMT approach has enabled wide spanning feature sizes over two orders of magnitude with 2 Å precision adjustments between samples. The PMT method is simple to validate with diffraction models and is feasible in any laboratory with minimal equipment. Finally, recent energy device research enabled by PMT is noted where tailored nanomaterials provided a unique perspective to unravel complex battery behaviors (ref. 2).
