Triptycene based luminescent metal–organic gels for chemosensing

Abstract

We report a novel luminescent Al-based metal-organic gel G1 comprising 1,4,5,8-triptycenetetracarboxylic acid, which exhibits highly sensitive detection towards nitro aromatic compounds particularly picric acid. Furthermore, under identical reaction conditions, using a Co(II) salt instead, a novel 3D framework material, trip-MOF-1, was isolated and its sensitivity towards picric acid was also evaluated.
