Emergence of a thorium-organic framework as a radiation attenuator for selective X-ray dosimetry

By first applying a thorium-organic framework (Th-SINAP-2) as a radiation attenuator and by incorporating a terpyridine derivative (Htpbz) as a photo-responsive guest, selective photochromism in response to X-rays was achieved in the host-guest assembly of Htpbz@Th-SINAP-2. Such a combination endows...

Description
Summary:By first applying a thorium-organic framework (Th-SINAP-2) as a radiation attenuator and by incorporating a terpyridine derivative (Htpbz) as a photo-responsive guest, selective photochromism in response to X-rays was achieved in the host-guest assembly of Htpbz@Th-SINAP-2. Such a combination endows the afforded material with the lowest detection limit of X-ray dose among all photochromic sensors and a brand-new function of X-ray dosimetry for thorium containing materials. A brand-new functionality of thorium has been achieved by employing a thorium-organic framework as an X-ray attenuator and a host of photo-responsive ligands, which allows selective chemosensing and sensitive dosimetry of X-ray radiation.
