Fig. 1: Uniform tilings and employed molecular precursors.
From: Complex k-uniform tilings by a simple bitopic precursor self-assembled on Ag(001) surface
a–c Example of regular and k-uniform tilings of Euclidean plane comprising two type of tiles: triangles and squares. The distinct types of vertices are marked by arcs. There is one type of vertex in regular tiling (a), two types in 2-uniform (b), and three types in 3-uniform tiling (c), respectively. d Chemical structure of 4,4’ biphenyl dicarboxylic acid (BDA) and (e) models of BDA with distinct level of carboxylation.
