“…It is well-documented in literature that a range of stimuli such as temperature, solvents, redox potential, acids, bases, metal ions, mechanical forces, etc., can stimulate spiropyran’s reversible isomerization [ 144 , 145 , 146 , 147 , 148 , 149 ]. Based on the properties mentioned above, increasing effort has been made to create spiropyran appended novel materials over the decades [ 150 , 151 , 152 ]. In 2014, Chen and Zhu et al created a family of antibacterial peptides (P SP −1, P SP −2, and P SP −3, Figure 7 A), of which SP units were linked to both ends of the sequence in accordance with varying chain lengths [ 153 ].…”

Over the last couple of decades, stimuli-responsive supramolecular gels comprising synthetic short peptides as building blocks have been explored for various biological and material applications. Though a wide range of stimuli has been tested depending on the structure of the peptides, light as a stimulus has attracted extensive attention due to its non-invasive, non-contaminant, and remotely controllable nature, precise spatial and temporal resolution, and wavelength tunability. The integration of molecular photo-switch and low-molecular-weight synthetic peptides may thus provide access to supramolecular self-assembled systems, notably supramolecular gels, which may be used to create dynamic, light-responsive “smart” materials with a variety of structures and functions. This short review summarizes the recent advancement in the area of light-sensitive peptide gelation. At first, a glimpse of commonly used molecular photo-switches is given, followed by a detailed description of their incorporation into peptide sequences to design light-responsive peptide gels and the mechanism of their action. Finally, the challenges and future perspectives for developing next-generation photo-responsive gels and materials are outlined.

“…Light is a green and appealing trigger due to its remote control, noninvasiveness and nondestructive nature, and availability. 248 250 The "trimethyl lock" effect, known since the 1970s, is used to release desired small molecules through polymer chain degradation via electrochemical, enzymatic, or mild chemical reagents and mediated two-electron reduction. Mutlu and co-workers synthesized recyclable polyethylene employing ADMET polymerization of ethylene and TMBQ derivatives using Hoveyda− Grubbs second-generation catalyst to incorporate the redoxresponsive unit into the polyolefin backbone for on-demand degradation in the presence of reductant agents such as sodium dithionate.…”

Polyolefins play a crucial role in the polymer industry because of their low-cost monomers and well-established production processes. Recent years have witnessed tremendous progress in direct and tandem copolymerization strategies that provide an opportunity of developing polyolefins bearing polar groups with distinctive architectures and properties. In this perspective, we first highlight new routes for the proficient synthesis of tailor-made functional polyolefins and briefly discuss their designing tactics. Then, we attempt to categorize these, recently appeared in the literature, innovative functional polyolefins on the basis of their applications. The prospected future applications of polar olefin copolymers include biomedical materials, catalysts, energy storage devices, and conductive polymers, which open up new arenas and paradigms for academic research and industrial products development. Critical issues concerning intelligent functional polyolefins and green chemistry are discussed, too.

Photoswitchable fluorescent materials are desirable for many applications because their emission signals can be easily modulated on demand. In this study, novel photoswitchable multistate fluorescent supramolecular polymers (PMFSPs) were prepared via host−guest interactions under a facile ultrasonication strategy. In the system, photochromic fluorescent diarylethylene monomer (SDTE, donor) and adamantane-containing monomer (BAC) were covalently combined into the backbone of the guest polymer (P1) via radical copolymerization. Meanwhile, the host moiety (CDSP, acceptor) was synthesized by covalent incorporation of photochromic spiropyran dye (SPCOOH) with β-cyclodextrin. By adjusting the stimulation wavelength and utilizing photoinduced fluorescence resonance energy transfer (FRET), the supramolecular polymers can undergo reversible tristate fluorescence switching among none, red, and green. In addition, due to the high contrast, rapid photoresponsiveness and prominent photoreversibility of the prepared PMFSPs, we demonstrated that they have great potential in advanced anti-counterfeiting and multilevel information encryption.
