Iminoguanidines: from anion recognition and separation to carbon capture

Journal Article · · ChemComm
DOI:https://doi.org/10.1039/D0CC04332J· OSTI ID:1657956
Iminoguanidines, first reported in 1898, have received renewed attention in the last 5 years due to their ability to recognize and separate anions from competitive aqueous environments. Iminoguanidines display high recognition abilities towards hydrophilic oxyanions (e.g., sulfate, chromate, carbonate) through strong and complementary hydrogen bonding from the guanidinium groups. Here, this feature article reviews the fundamental anion recognition chemistry of iminoguanidines, as well as real-world applications including sulfate removal from seawater and CO2 capture for climate change mitigations.
