      abstract     = {Minor actinide (MA) selective materials that are resistant
                      to radiation are necessary to enable separation of MAs from
                      lanthanides in nuclear wastes. Zirconium(IV) phosphonates
                      (ZrPs) are a class of amorphous coordination polymers with
                      promising applications as a solid-phase sorbent for
                      MA-lanthanide separations. In this study, a zirconium
                      phosphonate sorbent (ZrPTP) that intramolecularly
                      incorporates the MA-selective
                      2,6-bis(1,2,3-triazol-4-yl)pyridine (PTP) ligand was
                      synthesised and evaluated for radiation tolerance with high
                      energy electron irradiation to doses of 2 MGy. The MA
                      sorption selectivity of ZrPTP before and after irradiation
                      was compared using Am and Eu. ZrPTP demonstrated maintained
                      selectivity for Am over Eu even after a 2 MGy dose.
                      Synchrotron radiation characterisation techniques and
                      solid-state NMR were employed to accurately assess the
                      average local structure before and after irradiation, where
                      minor amounts of Zr–O bonds, aliphatic C–H bonds, and
                      triazole groups were broken, showcasing excellent radiation
                      stability for doses up to 2 MGy. Our results demonstrate the
                      importance of chemistry in ZrP coordination polymers
                      maintaining not only selective separation properties, but
                      also maintaining radiation stability as well.},
