Inspired by human vision, a diverse range of light‐driven molecular switches and motors have been developed for fundamental understanding and application in material science and biology. Recently, the design and synthesis of visible light‐driven molecular switches and motors have been actively pursued. This emerging trend is partly motivated to avoid the harmful effects of ultraviolet light, which was necessary to drive the classical molecular switches and motors at least in one direction, impeding their employment in biomedical and photopharmacology applications. Moreover, visible light‐driven molecular switches and motors are demonstrated to enable benign optical materials for advanced photonic devices. Therefore, during the past several years, visible light‐driven molecular switches based on azobenzene derivatives, diarylethenes, 1,2‐dicyanodithienylethenes, hemithioindigo derivatives, iminothioindoxyls, donor‐acceptor Stenhouse adducts, and overcrowded alkene based molecular motors have been judiciously designed, synthesized, and used in the development of functional materials and systems for a wide range of applications. In this Review, we present the recent developments toward the design of visible light‐driven molecular switches and motors, with their applications in the fabrication of functional materials and systems in material science, bioscience, pharmacology, etc. The visible light‐driven molecular switches and motors realized so far undoubtedly widen the scope of these interesting compounds for technological and biological applications. We hope this Review article could provide additional impetus and inspire further research interests for future exploration of visible light‐driven advanced materials, systems, and devices.

Advances in Application of Azobenzene as a Trigger in Biomedicine: Molecular Design and Spontaneous Assembly

Azobenzene is a well‐known derivative of stimulus‐responsive molecular switches and has shown superior performance as a functional material in biomedical applications. The results of multiple studies have led to the development of light/hypoxia‐responsive azobenzene for biomedical use. In recent years, long‐wavelength‐responsive azobenzene has been developed. Matching the longer wavelength absorption and hypoxia‐response characteristics of the azobenzene switch unit to the bio‐optical window results in a large and effective stimulus response. In addition, azobenzene has been used as a hypoxia‐sensitive connector via biological cleavage under appropriate stimulus conditions. This has resulted in on/off state switching of properties such as pharmacology and fluorescence activity. Herein, recent advances in the design and fabrication of azobenzene as a trigger in biomedicine are summarized.

Photoresponsive supramolecular switches refer to these host-guest systems that can be reversibly shifted between different states by light stimuli. Such photoswitchable systems feature the presence of non-covalent bonding interactions with light-responsive moieties (e. g., azobenzene and stilbene, spiropyran and diarylethene, coumarin and anthracene), and have been applied in a variety of fields, such as drug delivery, tissue engineering and smart materials with the advantage of being able to operate cleanly and remotely in a spatiotemporally-controlled fashion. Alternating UV/visible light irradiation can reversibly regulate the binding affinity or assembly/disassembly of the systems. This minireview summarizes recent progress (2016 and after) on the development of photoswitchable host-guest systems, including the structural designs of these molecular switches and their applications in solution and solid states. Better knowledge of them is essential for the understanding of host-guest phenomena, molecular machines, and also for the preparation of novel applied materials in the future.
