Abstract

A newly constructed hexanuclear cadmium metal–organic framework (MOF) exhibits a highly selective and sensitive fluorescence‐quenching response toward Fe 3+ ions, which is attributable to the coaction of absorption competition and an energy‐transfer mechanism.

Abstract

A hexanuclear CdII metal-organic framework (1) based on 4-(1H-pyrazole-4-carboxamido)benzoic acid (H2L) and featuring a three-dimensional microporous framework was synthesized. Notably, 1 shows a unique fluorescence-quenching response toward Fe3+ ions with high selectivity and sensitivity (Stern-Volmer constant KSV = 2.07 × 104 M-1). The response is attributable to the coaction of absorption competition and energy-transfer (ET) mechanism. Furthermore, spectral analysis indicates that the energy-transfer mechanism makes the dominant contribution to the fluorescence quenching of 1. [ABSTRACT FROM AUTHOR]
