“…The sonochemical synthesis of 3D microporous [Zn 2 (oba) 2 (bpy)] ( 1 ; H 2 oba = 4,4-oxybisbenzoic acid and bpy = 4,4-bipyridine) linkers has been reported by Moradi et al 86 for the development of luminescence sensors for the detection of Fe 3+ ions. The obtained photoluminescence intensity was sensitive to the type of solvent used, with MeOH showing the best performance among other solvents (ethanol, acetonitrile, THF, DMF, water).…”
