This research focuses on the development of lightweight, thermostable dual-function materials for secondary radiation protection and sensing by the integration of hydrogen-rich aliphatic chains inside the porous matrix of covalent-organic frameworks (COFs). The main aims of this project are the synthesis of organic linkers for forming a robust porous COF, synthesizing the porous COF through a condensation reaction, the development of hydrogen-rich aliphatic chains, and integration of aliphatic chains into COFs through click chemistry. This manuscript outlines the methodology and development of a novel self-assembled crystalline, porous material engineered to combine the functions of a shield and sensitive dosimeter. The reported hydrogen-rich materials are the first examples of COFs displaying stability in a wide range of pH (1–12), low-density, and thermal stability for advancing the space suit technology.


This research project focuses on developing materials for a dual sensing and protecting space suit by integrating thermally and chemically stable, crystalline, porous covalent-organic frameworks (COFs) in order to address current demands in lightweight, thermostable, hydrogen-rich materials for secondary radiation protection. These materials have the potential to significantly advance personal protection of astronauts on space missions through integration into a Sewable Attenuating Framework Equipped-Sensor (S.A.F.E.) space suit.The dual-function of hydrogen-decorated COFs contribute to the design of a S.A.F.E. space suit by offering both protection against radiation and acting as a sensitive dosimeter
