AI Technical Summary

Technical Problem

In the existing technology, the yield of gold nanorod assemblies is low and the orientation is bent, which affects the success rate of molecular electronic devices and their connection with external circuits.

Method used

Heterocyclic assemblies, comprising aromatic heterocycles, sulfur-containing anchoring groups, and groups or atoms capable of forming hydrogen bonds, are used to connect gold nanorods through coordination bonds and hydrogen bonds, forming assemblies with high yield and linear orientation.

Benefits of technology

High yield and linear orientation of gold nanorod assemblies were achieved, solving the problems of low assembly yield and orientation bending in traditional methods, and improving the fabrication success rate and connection stability of molecular electronic devices.

Abstract

The application belongs to the field of material chemistry and molecular electronics, and discloses a preparation method of gold nanorod assembly. The method comprises the following steps: providing a dispersion system containing a plurality of gold nanorods in a liquid medium; introducing a heterocyclic assembly molecule anchored on the surface of the gold nanorod into the dispersion system, wherein the heterocyclic assembly molecule contains a structural rigid aromatic heterocycle, a sulfur-containing anchoring group forming a coordination bond with the gold surface, and a group or atom capable of forming a hydrogen bond; the gold nanorod assembly contains at least two gold nanorods and the heterocyclic assembly molecule on each gold nanorod, and the two gold nanorods are connected by the hydrogen bond supramolecular interaction between the complementary functional groups of the heterocyclic assembly molecules. The preparation of the gold nanorod assembly with high yield and linear orientation is realized by using the heterocyclic assembly molecule.
