“…Recently, the photoinduced molecular orientation of MWCNTbased hybrid films by the photoisomerization of Sudan III azo dyes has been reported. [193] These hybrids exhibit electrical conduction properties in single-film-systems. Furthermore, the MWCNTs were non-covalently functionalized using molecular glue AB-based tetraphenylethylene 81 (Figure 19e).…”

The introduction of photochromism into nanosystems has resulted in the development of a class of light‐driven functional hybrid nanomaterials. Photochromic molecules have remarkable potential in memory and optical devices, as well as in driving and manipulating molecular motors or actuators and many other systems using light. When photochromic molecules are introduced into carbon nanomaterials (CNMs), the resulting hybrids provide unique advantages and create new functions that can be employed in specific applications and devices. In this review, we highlight the recent developments in diverse photochromic CNMs. Photochromic molecules and CNMs are also introduced. The fundamentals of different photochromic CNMs are discussed, including design principles and the types of interactions between CNMs and photochromic molecules via covalent interactions and non‐covalent bonding such as π−π stacking, amphiphilic, electrostatic, and hydrogen bonding. We then highlight the properties of photochromic CNMs, e.g., in photopatterning, fluorescence modulation, actuation, and photoinduced surface‐relief gratings; and their applications in energy storage (solar thermal fuels, photothermal batteries, and supercapacitors), nanoelectronics (transistors, molecular junctions, photo‐switchable conductance, and photoinduced electron transfer), sensors, and bioimaging. Finally, we present an outlook on the challenges and opportunities in the future of photochromic CNMs. This review discusses a vibrant interdisciplinary research field and is expected to stimulate further developments in nanoscience, advanced nanotechnology, intelligently responsive materials, and devices.This article is protected by copyright.

“…The Langmuir technique allows the creation of a large area of highly organized structures without the need for vacuum conditions . Despite the L method being designed for small amphiphilic molecules as fatty acid, it can be easily adapted for other materials such as small molecules, nanorods, nanocrystals, fullerenes, carbon nanotubes, ,− and many others. Kondej et al investigated the interactions of SWCNHs with lipids in the model membrane at the water–air interface in relation to health effects from nanoparticle inhalation and potential medical applications of SWCNHs.…”

A suspension of single-walled carbon nanohorn (SWCNH) aggregates with a size of approx. 50 nm was used to create a floating film at the water–air interface. The film was then transferred onto large-area quartz substrates using the Langmuir–Schaefer technique at varied surface pressures. The packaging and arrangement of SWCNHs in the film can be controlled during the process. The resulting films’ optical and electrical properties were investigated, and the highest electrical conductivity and figure of merit parameter values were observed for the film transferred at surface pressure near the collapse point. These films had a surface density of less than 5 μg cm–2, making them ideal for use in ultra-light sensors, supercapacitors, and photovoltaic cell electrodes. The preparation and properties of the Langmuir–Schaefer films of carbon nanohorns are reported for the first time.
