摘要：

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 CArH⋯O=C H bonds. In the crystal they form the mathematically predicted densest all-pentagon 2D lattice with a packing density of 0.921 (see picture). Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
