We will discuss the chemistry of new stimuli-responsive metallogels, the sensitivity of which can be controlled by “intentional defects” introduced to the tightly knit metal-organic networks. Built with multidirectional/multidentate ligands and various transition metal ions, these soft materials display markedly different rheological properties depending on the composition and relative ratio of the building blocks. In addition, a reversible sol-gel transition could be driven by the assembly and disassembly of metal-ligand bonds. This process was monitored by dramatic changes in the mechanical properties of the bulk material, as well as by colorimetric response of entrapped indicator molecules. To take this proof-of-concept prototype to the next level, we have constructed a controlled gas flow system to detect volatile acids using optimized zinc metallogels as dual-response chemosensors.
