Rapid synthesis of nanoscale terbium-based metal–organic frameworks by a combined ultrasound-vapour phase diffusion method for highly selective sensing of picric acid†
Abstract
A combined ultrasound-vapour phase diffusion technique was used for the rapid synthesis of a terbium-based metal–organic framework (MOF), [Tb(1,3,5-BTC)]n. Compared with conventional solvothermal and ultrasound-assisted methods, such a kind of combined ultrasound-vapour phase diffusion technique is highly sufficient for synthesizing nanoscale MOF crystals in remarkably high yields. Significantly, the as-prepared [Tb(1,3,5-BTC)]n
