具有热致双连续正交相结构的荧光液晶材料及其制备方法
By designing cyanostilbene-based small molecules with substituents introduced at the 3 and 5 positions of the benzene ring, the liquid crystal phase structure was regulated, solving the problem that existing liquid crystal materials are difficult to form three-dimensional continuous networks. This enabled the construction of three-dimensional continuous liquid crystal structures, enriched the behavior of liquid crystal phases, and expanded their applications in optoelectronic materials and nanostructure templates.

AI Technical Summary
Existing liquid crystal materials suffer from complex molecular structures, high synthesis costs, difficulty in forming three-dimensional continuous network structures, limited liquid crystal phase types, and insufficient synergy between functionality and structure, which restricts their application potential in optoelectronic functional materials.
By using relatively simple cyanostilbene-based small molecules, the length of the alkyl tail chain is changed by introducing substituents at the 3,5 positions of the benzene ring, thereby controlling the molecular stacking mode and inducing the formation of a three-dimensional continuous network liquid crystal phase structure, thus realizing the transformation from cubic phase to orthorhombic phase.
A three-dimensional continuous liquid crystal structure based on a small molecule system was constructed. It has the characteristics of simple structure and easy synthesis, breaks through the limitations of nematic phase, layered phase or columnar phase, enriches the liquid crystal phase behavior, has a three-dimensional periodic structure and connectivity, and is suitable for optoelectronic materials, chiral optical materials and nanostructure templates.
