摘　　要：The second example of tetravalent plutonium carboxyl-based organic framework,^(242)Pu(OH)[PO[(C_(6)H_(4))COO]_(3)]·H_(2)O,termed as PuTPO(TPO=tris(4-carboxylphenyl)-phosphineoxide),was reported in this work.A series of characterizations of PuTPO,such as X-ray crystallography and solid-state UV-Vis-NIR spectroscopy,were carried out to expatiate its structure and physicochemical properties.PuTPO is constructed by dimers of the plutonium-oxygen subunit of[Pu_(2)O_(16)].Characteristic peaks located at approximately 1100 nm can be considered to be the fingerprint peaks of tetravalent plutonium.While PuTPO can maintain high crystallinity within several months after synthesis,it exhibits a radiation-induced swelling effect probed by the expansion of cell parameter of b axis after self-irradiation fromα-decay of ^(242)Pu.This result enriches the inventory of tetravalent plutonium compounds and provides an insight into the irradiation resistance of metal-organic frameworks.
