Single-nanochannel X-ray diffraction on the liquid crystal C8BTBT confined in anodic aluminium oxide membranes — •Mark Busch1,2, Zhuoqing Li1,2, Milena Lippmann2, Andreas Schropp2, Johannes Hagemann2, Christian Schroer2,3, and Patrick Huber1,2 — 1TU Hamburg, Institut für Material- und Röntgenphysik — 2Deutsches Elektronen-Synchrotron DESY — 3Universität Hamburg
We investigate the self-assembly of the liquid crystal C8BTBT within anodic aluminium oxide (AAO) nanochannels in dependence of channel wall chemistry and the diameter of the channels from 60 to 180 nm. Conventional X-ray diffraction experiments use a comparatively large beam and therefore deliver a structural information which is averaged over a large number of nanochannels. In contrast here we investigate the structure of liquid crystals within individual nanochannels by employing an X-ray beam with a diameter in the nanometre range.
