摘要
We report optical, X-ray, polarization and response time measurements on a new 'banana-shaped' mesogen. The material has a salicylaldimine segment in the linear part of the core, but is otherwise structurally similar to the mesogen first reported to show a banana mesophase. Textural and X-ray studies show that this mesophase has all the characteristics of the recently discovered B-7 phase. It is observed that the voltage required to obtain electrical switching is quite low compared with values for the few other materials exhibiting the B-7 phase.
