Abstract

The invention relates to layer-by-layer self-assembly on the surfaces of substrates in a coordinate bond mode after a fully-conjugated photosensitive terpyridine derivative, namely 4'-(4-diazo)phenyl-(2, 2': 6', 2')-terpyridine fluoroborate (Diazo-tpy for short) modifies covalent bonds of multi-wall carbon nano-tubes, which belongs to the chemical field of functional materials, nanometer materials, and supramolecular self-assembly. Firstly, the Diazo-tpy is used to modify the covalent bonds of the multi-wall carbon nano-tubes; and secondly, the modified multi-wall carbon nano-tubes perform the layer-by-layer self-assembly on the surfaces of various functional substrates in the form of coordinate bonds to realize the full-conjugated assembly of the carbon nano-tubes and the substrates, andmetal particles are introduced to realize the further functionalization of the functional substrates. The method has simple, convenient and easy process as well as uniform and full modification, doesnot need special conditions and equipment, and can effectively control the deposition amount of the nano-tubes on the surfaces of the substrates through the number of assembly layers to realize the effective quantitative control of the performance.

Description

technical field

[0001] The present invention relates to a fully conjugated photosensitive terpyridine derivative 4'-(4-diazo)phenyl-(2,2':6',2")-terpyridine fluoroborate (abbreviated as Diazo- After tpy) covalently modify multi-walled carbon nanotubes, they self-assemble layer by layer on the surface of a substrate in the form of coordination bonds, belonging to the field of functional materials, nanomaterials, and supramolecular self-assembly chemistry. Background technique

[0002] Due to the unique mechanical, electrical, magnetic, optical and thermal properties of carbon nanotubes (CNTs), since the first discovery by Iijina in 1991, it has aroused great research enthusiasm among scientific and technological workers. According to different chiralities, single-walled carbon nanotubes (SWNTs) can exhibit metallic, semi-metallic, and semiconducting electrical conductivity. The energy gap between its conduction and valence bands can vary from 0 Ev to about 1 Ev. Scientists ...
