Identification and sorting of particle chirality using liquid crystallinity

Versatile homeotropic liquid crystal alignment with tunable functionality prepared by one-step method

“…There are a variety of other material technologies that can circumvent this problem while providing homeotropic alignment of LCs, which can be mainly divided into two categories, pretreatment and one-step methods. The pretreatment methods, including the one used for PI, require preparing the alignment layer on the substrates before use [16][17][18][19]. For example, alkyl trialkoxysilanes have been found to provide excellent homeotropic alignment for various LCs [20].…”
