The design of supramolecular templates to direct the synthesis of organized inorganic materials is illustrated for aragonite (CaCo 3 ), which is metastable under ambient conditions but found in gallstones, fish otoliths, etc. Spreading of the template 5‐hexadecyloxyisophthalic acid at the air/water interface is shown to result in the specific nucleation of aragonitc (see Figure) from supersaturated calcium bicarbonate solution without additives.
