An absorbing sorbent: A new series of [n]-oligoureas ([n]-OUs, n=4, 7, 10, and 12) green solid sorbents is prepared following a base-catalyzed, microwave-assisted oligomerization reaction. The reversible character of the CO2-capturing [n]-OU-based green sorbents is shown by performing sorption (35.0 °C) and activation/desorption (60.0 °C, in vacuo) experiments.
