Many molecules assemble into crystalline or disordered glassy structures on surface. With certain assembly approaches, specific molecules can be made to form ordered yet aperiodic structures, such as fractals and quasicrystals. Sierpiński triangles (STs) have been prepared on surfaces and in solutions through halogen bonding, metal-organic coordination, hydrogen bonding, and covalent bonding interactions.
