Abstract
The subject of the present invention is a method for controlling the spatial arrangement of domains of mesogenic compounds, exhibiting the ability to synchronise chirality by controlled synchronisation of conformational chirality, characterised in that an area of a thin film of a compound forming a conglomerate of domains is heated above the isotropisation temperature of a given compound until a specific chirality is obtained in a given area, and the shape of the heated area corresponds to a selected pattern enabling the control of the crystallisation front, wherein the heating is carried out by means of area illumination with laser light of a wavelength corresponding to the high absorbance of the melted compound and/or area heating of a substrate on which the thin film of the compound is placed and/or by area illumination with laser light of a wavelength corresponding to the high absorbance of a dye added to the film.
