Our research on the reversible self-gelation of ruthenium-based metal-organic polyhedra has been published in Chemical Science!! This work was led by our former postdoctoral researcher Dr. Javier Troyano, and it was finalized into a paper by the huge contributions from our Ph.D. candidates Fuerkaiti Tayier and Phitchayapha “Tang” Phattharaphhuti. Collaborations with Dr. Takuma Aoyama and Prof. Kenji Urayama booseted the understandings of gel formation process, from the rheological point of view.

Here we show, for the first time, the synthesis and controlled gelation of Ru(II,III)-based cationic MOPs. We investigated an interesting strategy of “self-gelation” driven by the charge of MOPs, which leads to the evolution of gels with permanent hierarchical porosity without using any additional component. This process is reversible, and the aerogel can be dissolved again to recover individual MOPs! This work also show an one-pot synthetic route from MOP precursors to prepare gels with the same porous properties.
