Fig. 1: Schematic illustration of QD patterns using LiXer.

a Schematic description of the ligand crosslinking process between neighbouring QDs based on the C–H insertion reaction of the nitrene moiety of LiXer. The inset shows the chemical structure of ethane-1,2-diyl bis(4-azido-2,3,5,6-tetrafluorobenzoate), used as the LiXer in this study. b Schematic description of the photo-patterning processes of QDs using LiXer. c Laterally positioned patterns and d vertically stacked patterns of RGB QDs, achievable from consecutive applications of the photo-patterning process.
