摘　　要：A highly stable fluorescent terbium MOF(Tb_(4)(paip)_(6)·1.2 H_(2) O,paip = 5-(1 H-pyrazole-4-yl)isophthalate)showing a sharp green emission(545 nm) and a quantum yield of 21.0% was successfully synthesized.This compound is shown to be a recyclable sensor for detecting picric acid in aqueous solution with both high sensitivity and selectivity,attributed to the electron transfer quenching mechanism.
