The dynamic behaviors of a new type of three-dimensional (3D) water framework symbiotic with 1D stacking organic guests, including an order-disorder transition of hydrogen atoms, a supercooling phenomenon during phase transition, and a dipole-glass-like relaxation behavior due to locally trapped water molecules, are presented. This extremely scarce 3D water framework, together with the rich dynamic behaviors it exhibits, provides new clues to design new ice-like models for promoting the fundamental understanding of the dynamic behavior of water in diverse solid-states.
本文展示了一种与一维堆积有机客体共生的新型三维(3D)水框架的动态行为,包括氢原子的有序-无序转变、相变过程中的过冷现象以及由于局部捕获水分子导致的类偶极玻璃弛豫行为。这种极其罕见的三维水框架及其所展现出的丰富动态行为,为设计新的类冰模型提供了新线索,有助于推动对不同固态水中动态行为的基本理解。
