A review. Three isomers were prepared by covalently grafting carbazole (Cz) onto spiro[fluorene-9,9′-xanthene] (SFX) at different positions. Due to the complicated and variable roles of mol. segments, an evolution of the corresponding mol. packing mode was realized, accompanied by the change of nanocrystal morphol. and photoluminescence properties.
