An enantiopure ligand built from connecting the Ïâ¯Ï stacking 1,8-naphthalimide supramolecular synthon with L-asparagine, Lasnâ, forms tetrameric [Cu4(Lasn)8(py)(MeOH)]. The methanol ligand, located in a chiral pocket, is replaced enantioselectively when exposed to racemicethyl lactate vapor to yield [Cu4(Lasn)8(py)((S)-ethyl lactate)], in a single-crystal to single-crystal gas/solid transformation.
