The structures and their orientation were measured in real time with synchrotron X-ray scattering. Incorporation of mesogenic groups with marked dipolar properties is a key element in this process. A mechanism related to the dissociation of hydrogen bonds is proposed to account for the fast orientation switching of the hydrogen-bonded blends.journal article10.1002/adfm.2003051592-s2.0-2342630583WOS:000221209400008https://api.elsevier.com/content/abstract/scopus_id/2342630583
