| titleOfInvention | Fluorescent organic-inorganic silicon oxide liquid crystal material and preparation method thereof |
| abstract | The invention belongs to the field of circular polarization luminescent materials, and particularly relates to a fluorescent organic-inorganic silicon oxide liquid crystal material and a preparation method thereof, wherein the preparation method comprises the following steps: the fluorescent organic-inorganic silicon oxide liquid crystal material is obtained by dissolving and mixing liquid crystal molecules, fluorescent molecules and chiral dopants and carrying out a cross-linking reaction, wherein the liquid crystal molecules are nematic phase liquid crystal molecules with trialkoxysilyl at the tail end, and the fluorescent molecules are tetraphenylethylene derivatives with AIE effect. The method firstly self-assembles into a spiral structure, and then obtains the organic-inorganic silicon oxide film with a cholesteric phase structure through the hydrolytic crosslinking of trialkoxysilyl at the tail end, and the whole process does not need to add a template agent, so the operation is simple; the tetraphenylethylene derivative with AIE effect is adopted, the derivative can emit light in a solid state, and the fluorescent molecule has high quantum efficiency; the obtained material has high luminescent asymmetry factor value and quantum yield. |
