Abstract

Abstract : 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. Abstract : 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.
