Hybrid One-Dimensional Nanostructures: One-Pot Preparation of Nanoparticle Chains via Directed Self-Assembly of in Situ Synthesized Discrete Au Nanoparticles
The fabrication of well-defined one-dimensional (1D)
arrays is
becoming a challenge for the development of the next generation of
advanced nanodevices. Herein, a simple concept is proposed for the
in situ synthesis and self-assembly of gold nanoparticles (AuNPs)
into 1D arrays via a one-step process. The results demonstrated the
formation of nanoparticle chains (NPC) with high aspect ratio based
on discrete Au nanoparticles stabilized by short thiol ligands. A
model was proposed to explain the self-assembly based on the investigation
of several parameters such as pH, solvent, temperature, and nature
of the ligand on the 1D assembly formation. Hydrogen bonding was identified
as a key factor to direct the self-assembly of the hybrid organic–inorganic
nanomaterials into the well-defined 1D nanostructures. This simple
and cost-effective concept could potentially be extended to the fabrication
of a variety of hybrid 1D nanostructures possessing unique physical
properties leading to a wide range of applications including catalysis,
bionanotechnology, nanoelectronics, and photonics
