摘要：

Rod-like naphthalene and the molecule 4,-(7,-(4,-(triphenylene-2,3,6,7,10,11-hexaylhexakis(oxy))hexakis(butane-4,1-diyl))hexakis(oxy)hexakis(naphthalene-7,2-diyl))hexakis(oxy)hexakis(butane-4,1- diyl) hexaacrylate, to which an acryloyl group that enabls photo-polymerisation is introduced, are synthesised nearby discotic triphenylene. Differential scanning calorimetry shows that a liquid crystalline form is observed at 69 degrees C. In XRD measurements, a new peak appears at 2 theta = 22, indicating partial nematic liquid crystalline properties. As a result of photo-polymerisation, successful polymerisation of over 70% is verified through FT-IR. UV-vis spectroscopy was used to measure the transmittance of the polymerised film, demonstrating a high transmittance level of over 94%.
