Metal organic framework

Abstract

An object of the present invention is to provide a MOF that exhibits greater than or equal to a predetermined adsorption amount at a high relative pressure while the amount of a target material to be adsorbed is rapidly increased according to the variation in relative pressure. The present invention is a metal organic framework, wherein on an adsorption-side isotherm of water vapor measured at 25° C., an inclination of a tangent line drawn at a point where a gradient of a curve is maximum is 7000 mL(STP)·g−1/relative pressure (P/P0) or more, a water vapor adsorption amount at a relative pressure (P/P0) of 0.96 is 440 mL(STP)·g−1 or more on the adsorption-side isotherm, and a vertical axis of the adsorption-side isotherm represents a water vapor adsorption amount and a horizontal axis of the adsorption-side isotherm represents a relative pressure (P/P0).
