Examples of the self-assembly of nanoplates (NPls) in colloidal suspensions have been reported for CdSe. These stacks can be considered as 1D superlattices with colloidal stability, and changes in the optical properties of the NPls occur upon aggregation. For instance, Tessier et al., have shown enhancement of the exciton-phonon coupling, evidenced by a side band in the emission spectrum, due to the formation of stacks of CdSe NPls. In a different work, Guzelturk et al. reported nearly 100% efficient Förster resonant energy transfer (FRET) within the stacks of CdSe NPls. The stacking resulted in a strong reduction of the PLQY, which the authors attributed to trapping of excitons in small-bandgap, non-emissive NPls. One last example is the work of VanOrman et al., in which the authors use CdSe NPls as a triplet sensitizer in a molecular up-conversion system based on triplettriplet annihilation. The authors argue that, when there is aggregation of the NPls, the upconversion dynamics is compromised. Nonetheless, while several examples are found for cadmium chalcogenides, to the best of our knowledge, there is no report in the literature on the self-assembly of PNPls in organic solvents. In addition, the common use of ethanol as an antisolvent as means to induce the stacking for cadmium chalcogenides may not be appropriate for PNPls, given the sensitivity of these materials to most polar antisolvents. Therefore, unraveling in which conditions the self-assembly of PNPls occurs in colloidal suspensions, or even exploring ways to finely control this aggregation, is of great importance to enable the investigation of their fundamental properties and further develop their applications.
