Abstract Self-assembling triblock molecules were previously shown to form thin films with polar order. These films are also known to contain polar supramolecular aggregates that are layered in head-to-tail fashion. In this work, glass substrates were prepared using a focused-ion-beam system to generate 1mm{times}1mm areas containing periodic arrays of squares with lateral dimensions of 7 and 17 {mu}m. The squares were defined by 3 {mu}m wide and 10 nm deep troughs created by Ga ion beams. Using second-harmonic-generation measurements, the average molecular tilt angle was found to be smaller in patterned films, suggesting that micropatterning enhances overall polarization in these films. {copyright} 2001 American Institute of Physics.
