生物基小分子在联苯类液晶材料合成中的应用进展

Progress on Biphenyl Liquid Crystal Materials Using Bio-Based Molecules

生物基小分子来源广、价廉,同时大多具有手性,使其在绿色化学盛行的今天作为良好的非介晶基元广泛应用于液晶材料合成研究领域。联苯类液晶因为其良好的物理化学稳定性、较宽的工作温度范围、适当的低黏度,以及快速响应与低电压驱动等优点,在光电显示材料等领域得到了广泛应用。文中综述了近年来薄荷醇、乳酸、糖醇、氨基酸等生物基小分子在联苯类液晶材料合成中的应用进展,指出多生物手性基团结合,特别是与高分子材料的完美组合,是未来研究的新方向。

Bio-based molecules have many advantages, such as wide source and low price. Most of them are chiral, so they can be widely used as good non-mesomorphous units in the synthesis of liquid crystal materials nowadays. Biphenyls liquid crystals were widely used in photoelectric display materials and other application areas for their many advantages, e.g., good physical and chemical stability, wide temperature range, appropriately low viscosity, fast response, and low driver voltage. The progress on the recent application of bio-based molecules, such as menthol, lactic acid, sugar alcohol, and amino acid, in the synthesis of biphenyl liquid crystal materials was reviewed. The combination of different biological chiral groups, especially with polymeric materials will be a new direction in the future.
