  - Supercrystals represent three-dimensional orderings of colloidal nanocrystals
    (NCs), showcasing collective properties in photonics, phononics, and electronics
    applications.1,2 Recent studies have shown that such assemblies are directly produced
    during nanocrystal reactions.3–6 However, a fundamental understanding of in situ
    formed supercrystals that withstand typical NC purification processes remains
    underexplored, which is important for further use. Herein, we report the reaction
    precursor-mediated formation of stable PbTe supercrystals. Rationalizing the formation
    of these assemblies through small-angle x-ray scattering (SAXS) measurements,
    we unveil their formation mechanism. Our findings reveal that the supercrystal
    formation occurs in the presence of an excess of lead oleates in the crude solution.
    It should be noted that the formed supercrystals can be stabilized under specific
    conditions determined by the lead oleate cluster concentration, content of trioctylphosphine
    telluride (TOP-Te), NC size and the need of an annealing step at mild conditions.
    Furthermore, this approach allows for the continuous growth of a secondary phase
    within the supercrystal; for example in the case of PbTe supercrystals, a PbS
    shell can be grown on each PbTe NC constituent, resulting in core-shell PbTe-PbS
    supercrystals. Our work elucidates that reaction precursors play an important
    role in in situ SC formation and stabilization, implying the possibility of applying
    this knowledge to other NC reactions.@eng
