a, Simplified representation of ST, 4MR and 6MR; oxotrimer size dimensions; calculated equations showing the relation between lengths of tightening-cSDA (LT) or expanding-cSDA (LE) and the length of tricarboxylate (LA). b, Map showing the close matches around the calculated equations for expanding-cSDA (orange) and tightening-cSDA (dark blue).
