Photoisomerization-mediated tunable pore size in metal organic frameworks for U(VI)/V(V) selective separation.

ABSTRACT: Selective extracting uranium from seawater is quite challenging, particularly the presence of vanadium, which poses a significant obstacle for most amidoxime absorbents. Adsorbents with size-matched pores and coordination environment can improve the uranium selectivity but usually deteriorate the adsorption capacity. Herein, a dynamically matched spatial coordination strategy is proposed to improve the performance of uranium extraction. The diarylethene (DAE) photoswitch with photoisomerization characteristic is introduced into Metal-Organic Frameworks (MOFs), in which the tunable pore size and coordination environment provide a precisely confined space for uranium capture under the dynamic adjustment of ultraviolet-visible (UV-Vis) irradiation.
