Decoding Liquid Crystal Oligomer Phase Transitions: Towards Molecularly-Engineered Shape Shifting Materials |
| 초록 |
This work details an integrated investigation of liquid crystal (LC) oligomers that combines experiments and molecular dynamics simulations for obtaining a detailed understanding of the molecular structure of LC oligomers and the mechanism underlying their phase transition temperatures. The results showed that increasing the length of the extender decreases Tni for LC oligomers and amplifies the decrease of Tni in LC oligomers when the spacer length is short. We infer that the combination of spacer and extender changes the shape anisotropy of LC oligomers, changing packing behavior of constituent mesogens, thus affecting their ability to transition from the isotropic to the nematic phase. |
