Nature Communications, Published online: 13 June 2026; doi:10.1038/s41467-026-74218-2 Liang et al. present flexible semiconductive polyMOF membranes, created by copolymerizing metal–organic frameworks with polymers. This integration reduces structural defects and improves charge transport, enabling highly sensitive X-ray detection with leading sensitivity and a conformal design suited for flexible dosimetry.
