Triptycene based luminescent metal-organic gels for chemosensing

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.

Synthesis and crystal structures of 1,4,8,11-Tetraalkyl-6,13- diphenylpentacenes

Two 1,4,8,11-tetraalkyl-6,13-diphenylpentacenes were prepared. X-ray analysis revealed that the methyl derivative had a herringbone arrangement with π-overlap, while the propyl derivative had a slipped-parallel structure without π-overlap. The solid-state
