AB  - When the micellar aggregation number ( N(agg)) is small enough (<30), the N(agg) 
      matches the value of vertexes of a regular polyhedron: Platonic solids, and 
      demonstrates perfect monodispersity. These micelles are named Platonic micelles 
      and are particularly found in the system of calix[4]arene-based micelles due to 
      the rigid structure of the backbone molecule. Although 
      sulfonatocalix[4]arene-based micelles are among the most studied host molecules 
      in supramolecular chemistry, their micellar properties as Platonic micelles have 
      thus far been overlooked. In this study, we prepared various 
      sulfonatocalix[4]arene-based amphiphiles bearing alkyl chains with different 
      lengths and investigated their aggregation behavior. When the amphiphiles formed 
      spherical micelles, they demonstrated monodispersity in terms of N(agg), whose 
      value changed from 4 to 17, and then to 24, upon increasing the carbon number in 
      each alkyl chain from C5 to C6, and then to C7, respectively. Although the 
      numbers 17 and 24 do not match the vertices of regular polyhedra, these values 
      can be reasonably explained by the Thomson problem, which considers the Coulomb 
      potential for calculating the best packing on a sphere with multiple identical 
      spherical caps. This study describes rediscovery of the monodispersity of 
      sulfonatocalix[4]arene-based micelles, which is consistent with the idea of 
      Platonic micelles.
