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

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