Liquid-Crystal Patterning: Lithographic Alignment of Discotic Liquid Crystals: A New Time–Temperature Integrating Framework (Adv. Mater. 46/2009)



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.
