Abstract
Porous materials which present open nanochannels of cross-sections ranging from 0.3 to 4 nm. were investigated. Particular attention has been given to microporous frilly-org. substances of synthetic or biol. origin. In the latter family, a no. of dipeptides crystallize in hexagonal lattices with permanent porosity and modulated pore sizes. The affinity towards CO2 and relevant gases, such as methane and hydrogen, and their absorption efficiency was proved for the first time, even under mild conditions. Moreover, mixt. sepns. has been tested successfully, due to the pronounced selectivity (e.g. CO2 vs N2 and CH4). Also, porous org. networks of extremely high surface area (>6000m2/g were prepd. and studied.).
