Liquid crystals are a successful example of how the control of self‐assembly via chemical design leads to novel applications. Massimiliano Cavallini, Fabio Biscari, and co‐workers report on p. 4688 that direct patterning of a continuous metal‐free mesogenic phthalocyanine film (discotic LCs) is achieved by spatial control of column orientation using unconventional lithography. These patterned films work as time–temperature integrators at the columnar rectangular–hexagonal transition temperature.
