摘要： A compound having a repeating unit represented by general formula (I)
A 1 -M 1 -X-B-Y-M 2 -A 2 (I)
wherein A 1 and A 2 are terminal chain groups, respectively; M 1 and M 2 are mesogen groups, respectively; X and Y are independently a bonding group selected from -COO- and -OCO-; and B is an aromatic group. The compound exhibits ferroelectric twisted grain boundary liquid crystalline properties over a wide range of temperature, and the crystal phases originating from such structure absorb light over a wide range of spectrum including visible light and, hence, are useful as a material for preparing light controlling devices, optical filters, recording devices, heat-sensitive ink, heat-sensitive pigments, toner pigments and the like, showing high industrial usefulness. Furthermore, the thermolabels, heat-sensitive recording media and the like of the present invention have high coloring and decoloring rates and are less expensive because of having no optically active group.
摘要翻译：具有通式（I）所示的重复单元的化合物A1-M1-X-B-Y-M2-A2（I）其中A1和A2分别为末端链基团; M1和M2分别是介晶基团; X和Y独立地为选自-COO-和-OCO-的键合基团; B是芳族基团。该化合物在很宽的温度范围内表现出铁电扭曲晶界液晶性能，并且源于这种结构的晶体相在包括可见光的宽范围光谱上吸收光，因此可用作制备光控制器件的材料，光学过滤器，记录装置，热敏油墨，热敏颜料，调色剂颜料等，显示出高工业实用性。此外，本发明的热敏标签，热敏记录介质等具有高的着色和脱色率，并且由于不具有光学活性基团而不昂贵。
