Planar,
terpyridine-based metal complexes with the Sierpiński
triangular motif and alkylated corners undergo a second self-assembly
event to give megastructural Sierpiński pyramids; assembly
is driven by the facile lipophilic–lipophilic association of
the alkyl moieties and complementary perfect fit of the triangular
building blocks. Confirmation of the 3D, pyramidal structures was
verified and supported by a combination of TEM, AFM, and multiscale
simulation techniques.
