AbstractTetranuclear copper(i) complexes containing N,N′-bis(5,7-dimethyl-1, 8-naphthyridine-2-yl)amine and phosphine ligands with close intramolecular Cu(i)⋯Cu(i) contacts were found to precipitate as thermodynamically stable and crystalline quasi-2D sheet-like nanostructures. Kinetically stable, amorphous, spherical particles were also identified during the precipitation/crystallization processes of these copper(i) complexes in a dichloromethane/hexane mixture. The distinct phosphorescent properties of these two forms of nanostructures were studied and a crystallization-induced emission enhancement was observed during the morphological evolution from amorphous spherical particles to crystalline nanosheets. All of these photophysical properties were rationalized by density functional theory calculations. © The Royal Society of Chemistry 2011.
