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/relative pressure (p/p) or more, a water vapor adsorption amount at a relative pressure (p/p) of 0.96 is 440 ml(stp)�gor 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/p).
