Complete twin suppression in oriented NH2-MIL-125 film via facile coordination modulation†
Abstract
Complete suppression of twin crystal formation in oriented metal–organic framework (MOF) film remains a great challenge. In this study, we successfully avoided the twin generation in c-oriented NH2-MIL-125 film through simple competitive metal ion-based coordination modulation. Simultaneously, relevant mechanism associated with twin suppression was elucidated.
