N2 - A porous cationic Ag(I) coordination polymer, [Ag(1,2,4,5-p4b)](SbF6)
(TJNU-302) with the ligand 1,2,4,5-p4b
(1,2,4,5-tetra(pyridin-4-yl)benzene), is reported that shows high
sorption capacity (211 mg g–1) and distribution coefficient Kd (5.8 × 105 mL g–1) as well as outstanding selectivity in 500 times excess of CO32– or PO43–
anion for perrhenate removal. TJNU-302 can act as a crystalline
turn-off sensor for perrhenate upon UV radiation. In this way, a test
paper strip for sensing ReO4– could be produced. In water solution, TJNU-302 shows an efficient fluorescence quenching response to ReO4– ion, with the highest quenching percentage (86%) among all reported ReO4–
sensors. These results could be elucidated by the bonding properties of
single-crystal structures of TJNU-302 before and after perrhenate
sorption, as well as density functional theory (DFT) calculations.
