The biogeochemical process known as mineral neogenesis has inspired the development of �accelerated aging�,[1] a novel method of synthesizing porous functional materials in a solvent-free, environmentally-friendly manner. Current concerns about environmental safety of chemical processes highlight the essential need for research into �greener� synthetic methods. Industrial-scale use of zeolitic-imidazolate-frameworks (ZIFs),[2] which are remarkable due to their porosity and potential for catalytic and separation applications,[3]is currently limited in part due to the input of thermal energy, solvents, and toxic reagents required for their synthesis. Accelerated aging is a mild, energy-efficient method of inducing the quantitative self-assembly of ZIFs from inert metal oxides and imidazoles under low temperature and humidity conditions, using an acidic salt additive as catalyst and templating agent.[1] Cliffe, M.
