Method for measuring reaction rate of reactive mesogen |
摘要 |
A method for measuring a reaction rate of a reactive mesogen and an alignment layer formed thereby, the method including coating an alignment material on a substrate. The alignment material includes a backbone and a reactive mesogen connected to the backbone. The reactive mesogen includes an unsaturated bond. The alignment material is irradiated with ultraviolet light, or is heated, to form the alignment layer. A marking compound, including a thiol group is coated on the alignment layer and reacts with remaining unreacted reactive mesogen, to form a marked mesogen. An amount of the marked mesogen is detected. A reactive ratio is measured by comparing an amount of the reactive mesogen before irradiating or heating with an amount of the marked mesogen. |

1. A method for measuring a reaction rate of a reactive mesogen comprising:
applying an alignment material to a substrate, the alignment material comprising alignment molecules that each comprise a backbone and a reactive mesogen connected to the backbone; reacting the reactive mesogen to form an alignment layer, by irradiating the alignment material with ultraviolet light having a first intensity, or by heating the alignment material; applying a marking compound comprising a thiol group to the alignment layer, the marking compound configured to react with any remaining unreacted reactive mesogen, thereby forming a marked mesogen; detecting an amount of the marked mesogen; and measuring a first reactive ratio by comparing an initial amount of the reactive mesogen with the detected amount of the marked mesogen. |
