Abstract

A dewetting process of an evaporating solution is used to form micrometer-sized amorphous droplets, or "domes", of organic compounds, both polymeric and low-molar-mass, on various substrates such as silicon, mica, glass, and indiumtin-oxide. The produced patterns are characterized by a regular 2-dimensional array of similar-sized domes. Here we report on the reversible shape change of polymeric domes (between lens and sphere) and the irreversible shape change of domes made of low-molar-mass compounds, e.g. due to crystallization. Control of crystallization leads to the formation of single crystallites of a non-linear-optically active p-nitro phenol salt.
