One-step synthesis and assembly of one-dimensional parallel chains of CdS nanoparticles at the air-water interface templated by 10,12-pentacosadiynoic acid supermolecules

► Parallel 1D chains of CdS nanoparticles were prepared at the air/water interface. ► These nanostructures were produced through one-step synthesis and assembly process. ► 10,12-pentacosadiynoic acid supermolecules in Langmuir monolayers acted as templates. ► The parameters of the nanostructures can be tuned.
