Abstract

, and excellent operational stability, with no degradation after a high cumulative x-ray dose of 148 Gy. Moreover, the fully environment-friendly composition ensures intrinsic environmental friendliness. This work not only validates COFs as a promising platform for high-performance, stable, and green x-ray detection, but also provides a molecular-level paradigm for designing next-generation low-dose radiation sensing materials.
