abstract = {Developing convenient and reliable synthetic methodologies
for solution processable 2D layered ultrathin nanostructures
with lateral size control is one of the major challenges for
practical applications. In this study, a rational
understanding a long-chain amphiphilic surfactant assisted
non-hydrolytic synthesis that is able to generate
dimension-controllable 2D-WS2 nanocrystal flakes in a
single-step protocol is proposed. The evolution of the
starting soft organic–inorganic lamellar template into
ultrathin few-layer 2D-WS2 nanostructures with lateral size
modulation over a range between 3 and 30 nm is monitored.
The initial formation of WS2 nanoseeds occurs in a
self-assembled sacrificial precursor source, acting as a
template, where larger two-dimensional nanostructures can
grow without undergoing significant thickness variation.
Overall, the chemical nature and steric hindrance of the
alkylamines are essential to modulate the reactivity of such
WS2 nanoclusters, which correlate with the lateral size of
the resulting nanoflakes},
