. We demonstrate that banana-shaped molecules 1,3-phenylene bis(4-methoxybenzylidene amine) can assemble themselves into diffraction gratings when the melt of the banana-shaped compound, which was sandwiched between two pieces of glass substrates, is cooled to room temperature. Polarizing optical microscopic characterization shows that a pattern of periodic modulation of the refractive index can be developed in the thin films formed by the banana-shaped compound. Despite the gratings are groove free, their optical properties are the same as classically ruled gratings. Our work provides an alternative method for manufacturing diffraction gratings by harnessing the self-assembly of banana-shaped molecules.

Banana-shaped liquid crystals can self-assemble themselves into one kind of thin films in which periodic modulation of the refractive index can be developed. When a beam of light is shone onto the thin films, diffraction patterns can be formed. In this work, the diffraction equation is derived for one-dimensional diffraction gratings formed by banana-shaped liquid crystals.
