Abstract Emerging applications of photochromic compounds demand new molecular designs that can be inspired by some long‐known yet currently forgotten classes photoswitches. In the present review, we remind community about Peri ‐AryloxyQuinones (PAQs) and their unique photoswitching behavior originally discovered more than 50 years ago. At heart this phenomenon is light‐induced migration an aromatic moiety (arylotropy) in peri ‐aryloxy‐substituted quinones resulting ana ‐quinones. PAQs feature absorbance both isomers visible spectral region, photochromism amorphous crystalline state, thermal stability photogenerated ‐isomer. Particularly noticeable high sensitivity ‐isomer towards nucleophiles solution. addition to mechanism underlaying structure‐switch relationships, analyze potential prospects aryloxyquinones optically switchable materials devices. Due ability efficiently photoswitch solid are indeed attractive candidates for such devices, including electronics (optically controllable circuits, switches, transistors, memories, displays), porous materials, actuators, photoactivated sensors, many more. This review intended serve as a guide researchers who wish use photoswitchable development photocontrollable processes.

Controlling supramolecular polymerization by external stimuli holds great potential toward the development of responsive soft materials and manipulating self-assembly at nanoscale. Photochemical switching offers prospect regulating structure properties systems in a noninvasive reversible manner with spatial temporal control. In addition, this approach will enhance our understanding mechanisms; however, control molecular assembly light remains challenging. Here we present photoresponsive stiff-stilbene-based bis-urea monomers whose

Furthermore, a new hypothesis aimed interpret integration effects multi-components traditional Chinese medicines (TCMs) inspired on theory assembly is proposed. Generally, this review can enlighten us achieve qualitative leap understanding from monomolecule multi-component interactions, valuable intensive research application.

Supramolecular systems are intrinsically dynamic and sensitive to changes in molecular structure external conditions. Because of these unique properties, strategies control polymer length, composition, comonomer sequence, morphology have be developed for sufficient over supramolecular copolymerizations.

Moreover, model was used predict impact an additive (chain capper intercalator) on concentrations, showing remarkable amplification efficiency at high concentrations.

Light is one of the non-invasive stimuli which can be used in spatiotemporal control chemical reactions. Over past decade, light has found wide applications polymer science such as synthesis, release small molecules from polymers and polymeric photosensors etc. Reviews on light-regulated polymerisations have predominately focused free radical process. However, marriage to non-radical polymerisations, e.g. ionic, ring-opening, metathesis, step-growth supramolecular photopolymerisations, also spurred tremendous research interest develop materials.

While the tremendous deal of efforts has been dedicated to design and fabrication materials with circularly polarized luminescence (CPL), development chiroptical switch between different CPL signals is one important routes toward its application. Here, we prepared a supramolecular gel from coassemblies containing chiral gelator (9-fluoren-methoxycarbonyl-functionalized glutamate derivatives, FLG), fluorescent molecule [(rhodamine B, RhB) or (2′,7′-dichlorofluorescein sodium salt, DCF)], photochromic [1,2-bis(2,4-dimethyl-5-phenyl-3-thienyl)-3,3,4,4,5,5-hexafluoro-1-cyclopentene, DAE], thus constructing photomodulated switchable soft materials. It was found that FLG could form in ethanol self-assemble into left-handed twisted nanostructures. During formation co-gel RhB (or DCF) DAE, chirality be effectively transferred both components, which induced them properties including circular dichroism (CD). DAE undergoes reversible transition achromatous open state dark purple closed under alternating irradiation UV visible light. such process, an intermolecular Förster resonance energy transfer (FRET) behavior ring-closed caused emission quenching RhB, led silence co-gel. Subsequent light restoration activity restored state. These changes repeated many times upon alternate irradiation. Therefore, fabricated gels through FRET process.
