The growth rate of spherulites in solution-processed, triethylsilylethynyl anthra-dithiophene thin films can vary by a factor of three depending on the surface energy of the underlying substrate. By selectively patterning the underlying substrate to have regions of different surface energies, Y.-L. Loo and co-workers show on page 2692 how they are able to guide crystallization along pre-specified, nonlinear patterns over large areas in the plane of the film.
