Abstract

original image

Current events: An electric-field-responsive handle (see picture) was developed that enables large-area and millimeter-thick unidirectional orientation of columnarly assembled π-conjugated liquid-crystalline molecules. The handles in the columns are hydrogen-bonded and align along the direction of an applied electric field.
