Abstract
Self-assembled synthetic hybrid materials are an important class of artificial materials with potential applications in various fields ranging from optoelectronics to medicine. The noncovalent interactions involved in the self-assembly process offer a facile way to create hybrid materials with unique and interesting properties. In this context, self-assembled hybrid materials based on carbon nanotubes (CNTs), graphene, and graphene derivatives such as graphene oxide (GO) and reduced graphene oxide (RGO) are of particular significance. These composites are solution processable, generally exhibit enhanced electrical, mechanical, and chemical properties, and find applications in the fields of light harvesting, energy storage, optoelectronics, sensors, etc. Herein, we present a brief summary of recent developments in the area of self-assembled functional hybrid materials comprising one-dimensional (1D) or two-dimensional (2D) carbon allotropes and synthetic π-systems such as aromatic molecules, gelators, and polymers.
Highlights
Strategies based on π–π interactions are found to be extremely suitable for making hybrid materials in combination with 1D and 2D carbon allotropes and thereby overcome a major drawback associated with solubility[19]
Carbon nanotube-based hybrid materials carbon nanotubes (CNTs) are an allotrope of carbon with a 1D nanotubular structure and are broadly classified as single-walled nanotubes (SWNTs), doublewalled, and multi-walled nanotubes (MWNTs)[11,23]
The various reports discussed in this review reiterate the importance of functional hybrid materials consisting of π-conjugated organic small molecules/polymers and gelators with CNTs/graphene/graphene derivatives in a wide range of applications
Summary
Carbon nanotube-based hybrid materials CNTs are an allotrope of carbon with a 1D nanotubular structure and are broadly classified as SWNTs, doublewalled, and multi-walled nanotubes (MWNTs)[11,23]. The electrical conductivity of CNTs ranges from metallic to semiconducting based on the diameter and the rolling angle, which impart chirality in the tubes[11]. CNTs have excellent chemical, mechanical, and electronic properties that make them promising for various applications. The noncovalent functionalization of CNTs with aromatic molecules and π-conjugated polymers has been extensively investigated[11–14,55–62]. The surface modification of CNTs through noncovalent interactions improves their dispersion and solution processability, rendering them suitable for device applications
