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.
