| Summary: | Title screen A first time report on a solid-state polymorphic transformation of MOF materials [Zn2(bdc)2(dabco)]n (ZnBD) and [Co2(bdc)2(dabco)]n (CoBD) from a pillared kagomй-lattice form (ZnBDkgm or CoBDkgm) to a pillared square-lattice form (ZnBDsql or CoBDsql) at ambient condition is given. Several solvents were applied as a guest-driven molecule to trigger the solid-to-solid transformation while only methanol demonstrated to be able to perform this transformation. The methanol-driven solid-state transformation behavior was observed by using powder X-ray diffraction. The morphology investigated that the rod-like Kagomй form rapidly transformed into a tubular square lattice upon addition of methanol at room temperature. The characteristic porosity reconfirmed the transformation was complete. A transformation mechanism of disconnection-deformation-rebuilding was elucidated based on the experiment.
