“Basic Research on Key Intrinsically Flexible Molecular Materials and Devices for Future Adaptive Deformation Displays”
Special Project Guide
In order to comply with the new round of scientific and technological revolution and industrial transformation trends, and to help tackle key core issues in new display technologies in the future, the Interdisciplinary Science Department of the National Natural Science Foundation of China (hereinafter referred to as the Natural Science Foundation of China) plans to establish the “Key to Future-oriented Adaptive Deformation Display” Fundamental Research on Intrinsically Flexible Molecular Materials and Devices” special project. Intrinsically flexible molecular materials refer to optoelectronic functional materials formed by the aggregation and assembly of functional molecules through weak intermolecular interactions. They have mechanical deformation properties such as stretchability, bending, and foldability from micro to macro levels. Future adaptive deformation display technology puts forward new requirements for core materials and devices. Traditional mechanical flexibility and structural flexibility are difficult to meet the requirements of high-resolution and high-reliability adaptive deformation display, while the inherent mechanical deformation performance and photoelectric function Flexible molecular materials can provide a unique technical path for adaptive deformation displays.
This project focuses on key scientific and technological issues such as the coupling mechanism of force-electricity-optical functions of intrinsically flexible molecular materials at the molecular level, regulation strategies, and device integration. It integrates chemical synthesis methods, material function regulation concepts and key information technologies to carry out multi-disciplinary Cross-research will provide scientific basis and basic support for key material creation and device construction in my country’s future adaptive deformation display industry.
