Scientists have developed a new dye-free photoalignment method that enables 2-D patterns of liquid crystals in one step by guiding nonpolarized light temporally and spatially on the photopolymerization process. This new method provides a pathway for the simple creation of highly functional organic materials such as flexible liquid crystal devices.
