Abstract |
Aside from the three most common states of matter, solid, liquid, and gas, there exists an intermediate phase of matter between the solid and liquid phase which has been characterized as a liquid crystal. Molecules in this state can flow like a liquid but have solid phase properties such as the ability to be active when placed in an electric field. Liquid crystals exist in phases distinguished by their increasing order between the molecules and include smectic C, smectic A, and nematic with smectic C having the most order. These compounds are used in optical switches, laser tuners, medical technology, but mainly in Liquid Crystal Displays (LCD). One aspect of these materials that has been problematic is their response time when activated by an electric field. These compounds are relatively slow to relax, on the order of milliseconds, however our research is directed toward making this response time much faster, possibly on the order of microseconds. We plan to do this by chemically synthesizing various new sulfur-based liquid crystals called thienothiophenes. These structures, through literature research, have been found to be under-studied, leaving a window of opportunity. Developing a liquid crystal with a faster response time can in fact increase resolution, leading to the development of a more advanced high definition display. The building blocks of these liquid crystals have been synthesized; however, future work will include the addition of various alkyl chains to test the differences in physical properties of these materials. |
