Regular pentagonal adhesive tiles were obtained by designing a cyclic fluoropentamer with an internal CF ⋅⋅⋅ HN H‐bonded network and “sticky” edges that can glue the molecules together through intermolecular C Ar H ⋅⋅⋅ OC H bonds. In the crystal they form the mathematically predicted densest all‐pentagon 2D lattice with a packing density of 0.921 (see picture).
