1. A method of extracting one or more target substance(s) from a target mixture comprising one or more target substance(s) and one or more non-target substance(s), the method comprising preferentially sorbing the target substance(s) over the non-target substance(s) by contacting the target mixture with a sorption composition, at a predetermined contacting temperature, to provide a sorbed composition and a treated target mixture;

wherein:

the sorption composition comprises a sorption compound, which is a porous organic cage comprising an internal cavity having a cavity size within +/−4 Å of the thermal de Broglie wavelength, at the contacting temperature, of the target substance(s);

the sorbed composition comprises the sorption composition with the target substance(s), or a mixture relatively enriched in target substance(s) as compared to the target mixture, sorbed therein; and

the treated target mixture is relatively enriched in the non-target substance(s) as compared to the target mixture;

wherein the target substance(s) have a shorter thermal de Broglie wavelength than the non-target substance(s).
