A Smart Bent-Core Liquid Crystal to Write Chinese Characters
We demonstrate that a bent-core liquid crystal 1,3-phenylene-bis(4-butoxybenzylidene amine) can write the Chinese character 人, which means a person in English, when the bent-core compound gets cooled from its isotropic phase. The polarized optical microscopic graphs illustrate that the bent-core molecules are able to self-assemble themselves into the Chinese character either in a sequential order or in a reverse order. Our results reveal that bent-core molecules have the capability of being smart materials.
