Odor-causing substances have been unfavorable targets for crystallographic analysis because they are usually volatile liquid or gas compounds, scarce amount of which can often be isolated from natural sources. Inclusion into a single crystal of porous coordination polymer “Crystalline Sponge” via vapor diffusion facilitates a single crystal in which the odor compound is regularly ordered, and enables its crystallographic structure analysis.
