A newly synthesized dual photo-functionalized amphiphilic supramolecules (abbreviated as AZDA) were successfully applied as a robust photo-reversible liquid crystal (LC) alignment layer by self-assembly and photo-polymerization without the conventional polymer-based LC alignment process. The chemical structure of AZDA was determined by 1H NMR, 13C NMR, MALDI-ToF, and elemental analysis. The dual photochemical behavior of AZDA was identified by ultraviolet-visible spectroscopy. The homeotropic alignment of nematic LC was investigated by both orthoscopic and conoscopic polarized optical microscopy. The self-assembled AZDA monolayer was investigated by atomic force microscopy to analyze the surface morphological changes of the AZDA layer according to light irradiation. This work was supported by the BRL 2015042417, MOTIE/KDRC 10051334 and the BK21 Plus program, Korea. |
