The Applied Supramolecular Chemistry Group (CSAp), from the Institut de Chimie et Biochimie Moleculaire et Supramoleculaire focuses on the selective and reversible capture of valuable molecules from complex mixture by self-assembling into soluble objects or nanomaterial. On of the axis is focused on the chemistry of CO2, the ultimate combustion product of organic resources which is extracted and valorized as a tecton (building block and molecular trigger) to build reversible and original nanomaterials by self-assembling (J. Am. Chem. Soc. 2010, 132, 3582-93).Spontaneous thermodynamically controlled aggregation into a highly organized nano-material (Chem. Sci., 2016, DOI: 10.1039/C5SC03810C), proves to be a highly selective process in terms of building block incorporation paving the way toward the capture and recycling of valuable molecules from complex mixtures. The use of a volatile tecton within a reversible supramolecular network also affords original and bioinspired properties such as cooperativity. Recently, this approach was successfully applied to the selective extraction of strategic metals from mixtures mimicking technological waste (PCT Int. Appl. 2014, WO 2014188115 A1 20141127; Green Chemistry 2017, DOI: 10.1039/c6gc02442d) and implemented into microfluidic processes (SATT Project Pulsalys, Fr. Patent 2016 16 53968)
