Rare-earth-pentacene-octacarboxylate frameworks for highly efficient urinary 1-HP fluorescence sensing

Abstract

A series of rare-earth metal–organic frameworks were synthesized based on a pentiptycene-octacarboxylic ligand. High-sensitivity and high-selectivity fluorescence sensing of 1-hydroxypyrene was achieved using the europium compound, with a rapid response time of merely 35 seconds and remarkable resilience to interferents.
