Pure organic phosphorescence has a high quantum yield and a property of maintaining a long decay time even when irradiation disappears, so it is used for biochemical sensors, bio-imaging, and OLED materials. In particular, the single-crystalline ice facets that have highly ordered organized OH groups at the surface were suitable to control the assembly of molecules as a template. In addition, ice has a unique characteristic called a quasi-liquid layer, which makes it suitable for organizing molecules into organic phosphorescent materials. In this research, when organic phosphorescent materials were grown using ice as a substrate, it was found that ice induces the arrangement of the phosphorescent materials and increases the triplet concentration of the phosphorescent materials. We theoretically discovered that quasi-liquid layers (QLLs), a unique characteristic of ice through Molecular dynamics (MD) simulations, enhance the diffusion of Br6A particles to form a new crystal structure. |
