Large-Scale Synthesis of Ultrathin Bi2S3 Necklace Nanowires

One of the most fascinating areas of nanoscience is the study of one-dimensional nanostructures.[1] From our materials chemistry viewpoint the idea of bringing the size of nanowires down to a point where nanoscale colloidal analogues of polymers can be studied is most stimulating. This direction has been the subject of intense study that promises to develop a new class of materials in which the topological properties of polymers can be coupled with quantum size effects and inorganic crystalline materials.[2, 3] Our strategy goes in a singular direction: instead of connecting nanocrystals by ligand chemistry[4] or dipole interactions[5] we aim to synthesize colloidal nanowires thin enough to display polymer-like behavior.
