Alternate D–A stacking has been used as a powerful strategy to achieve thermotropic liquid crystalline materials. Ringsdorf and co-workers showed CT-complexation- mediated induction of LC phases in otherwise amorphous main-chain and side-chain polymers with triphenylene donors in the presence of aromatic acceptors such as 2,4,7-trinitrofluorenone and 2,4,7-trinitrofluoren- 9-ylidenemalonodinitrile . The side-chain and main-chain polymers exhibit nematic-columnar and columnar hexagonal phases in the presence of approxiemtely 25% TNF owing to CT interactions. In the presence of a stronger acceptor, TNF-CN,the clearing temperature of the hexagonal phase can be enhanced to about twofold in comparison with that of TNF, thus suggesting not only induction of the mesophases but also modulation of the phase properties are achievable through CT interactions. |

Ringsdorf and co-workers showed CT-complexation- mediated induction of LC phases in otherwise amorphous main-chain and side-chain polymers with triphenylene donors in the presence of aromatic acceptors such as 2,4,7-trinitrofluorenone and 2,4,7-trinitro fluoren- 9-ylidene malononitrile . The side-chain and main-chain polymers exhibit nematic-columnar and columnar hexagonal phases in the presence of approximately 25% TNF owing to CT interactions. In the presence of a stronger acceptor, the clearing temperature of the hexagonal phase can be enhanced to about twofold in comparison with that of TNF, thus suggesting not only induction of the mesophases but also modulation of the phase properties are achievable through CT interactions. 非传统的D-A堆叠已被用作生产热致液晶 材料的重要手段。 Ringsdorf及其同事研究表明在芳香族受体诸如2,4,7 - 三硝基芴酮和2,4,7 - 三硝基芴 9 - 亚基丙二腈供体存在下，CT-络合 - 介导了其他一些带有三亚苯配体的非晶相主链和支链聚合物的液晶相诱导 。由于CT相互作用，在约25％TNF存在下，侧链和主链聚合物呈柱状向列相和柱状六角相。更强的受体存在时，六角晶相的相变温度与单独 TNF相比可提高到大约两倍。从而表明通过CT相互作用，不仅可以 诱导中间相，而且可以实现相位特性调控 。 悬赏金币太少，估计难有人应助，帮你翻译如上，部分认为有错的地方同时修改如上，请自己再核对一下！ |
