Fig. 2: Molecular-level insights into the solid-state chemical transformation of the HOPE system.
From: Chemical weathering of molecular single crystals to monoliths of quantum dots
a Schematic representation of the HOPE system transformation mechanism to ZnO QDs involving: (i) initial hydrolysis of [EtZn(BA)]4 cluster, (ii), formation of zinc hydroxide- and oxide intermediates, (iii), nucleation and growth of ZnO@BA QDs. b, c Time-resolved DRIFT (b) and the evolution of selected signals in time (c). d Time-resolved Raman studies on the transformation of HOPE towards ZnO QDs. e 13C CP-MAS and 15N CP-MAS NMR studies on the transformation of HOPE towards ZnO QDs. Asterisks (*) indicate emerging signals from amide group of free crystalline BA-H. Source data are provided as a Source Data file.
