    <description descriptionType="Abstract">&lt;p&gt;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-WS&lt;sub&gt;2&lt;/sub&gt;&amp;nbsp;nanocrystal flakes in a single-step protocol is proposed. The evolution of the starting soft organic&amp;ndash;inorganic lamellar template into ultrathin few-layer 2D-WS&lt;sub&gt;2&lt;/sub&gt;&amp;nbsp;nanostructures with lateral size modulation over a range between 3 and 30 nm is monitored. The initial formation of WS&lt;sub&gt;2&lt;/sub&gt;&amp;nbsp;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 WS&lt;sub&gt;2&lt;/sub&gt;&amp;nbsp;nanoclusters, which correlate with the lateral size of the resulting nanoflakes.&lt;/p&gt;</description>
