Highly stable and
porous water vapor adsorbents are of primary
importance in many water adsorption related applications such as moisture
control, adsorption desalination and adsorption heating/cooling pumps. However,
various difficulties have been experienced in synthesizing porous material combining
high porosity and exceptional stability and adequate structural properties
relationships.^1,2,3 In this paper, I will
demonstrate the last development in Molecular Building Block (MBB) approach to
assemble novel extremely highly porous and stable Metal Organic Frameworks
(MOFs) with water uptake ranging from 0.5 to 2 g/g (Figure1). In particular,
the structural properties with relation to the shape of water adsorption
isotherms and the mechanism of adsorption-desorption involved, will be debated.
