Liquid crystals are a successful example of how the control of self‐assembly via chemical design leads to novel applications. Direct patterning of a continuous metal‐free mesogenic phthalocyanine film (discotick liquid crystals) is shown by the spatial control of columns orientation by unconventional lithography. These patterned films work as time–temperature integrators at a columnar rectangular–hexagonal transition temperature.
