Summary: The study introduces a nanoporous solid material that induces chirality and enantioselective enrichment through circularly polarized light. Based on a crystalline metal-organic framework, the material utilizes photoswitchable fluorinated azobenzenes to induce chirality through trans-to-cis photoisomerization. Experimental results demonstrate that CPL causes chiral photoresolution, resulting in an optically active material.

Summary: Utilizing achiral fluorophores to achieve circularly polarized luminescence (CPL) is important but limited by chirality transfer. Inspired by biological light-harvesting systems, a new strategy called circularly polarized fluorescence energy transfer (CPF-ET) is proposed to explore multicolor CPL films without chirality transfer. CPL is successfully realized through both radiative and nonradiative energy transfer. Chiral fluorescent helical polyacetylene acts as a circularly polarized fluorescence energy donor, while achiral fluorophores serve as energy acceptors. This work provides a facile and versatile platform for achieving CPL by taking advantage of achiral fluorophores.

Summary: Modern sensing and imaging applications require accurate measurements of light wave properties such as intensity, wavelength, directionality, and polarization. This study demonstrates the use of engineered optical resonances in nanostructures to achieve selective detection of circularly polarized light. By patterning a thin silicon layer into a dislocated nanowire-array, it is possible to detect circularly polarized light with high efficiency. The presence of periodic dislocations enables selective excitation of nonlocal, guided-mode resonances for one handedness of light.

Summary: Through hydrothermal growth using chiral sugar alcohols as symmetry-breaking agents, chiral mesostructured bismuth oxybromide films were fabricated. These films exhibited optical activities over a wide wavelength range of 350-2500 nm and showed a significant chirality-dependent colour response to circularly polarized light, attributed to the hierarchically chiral arrangements of fine size.

Summary: This review systematically summarizes and discusses the application-guided design strategies of circularly polarized light (CPL)-responsive materials. CPL illumination enables the direct synthesis of helical polymers and chiral inorganic nanostructures, and their intramolecular folding and self-assembly are modulated by light. In the aggregated state and liquid crystal phase, the helical sense of molecular packing is sensitive to the enantiomeric bias brought by CPL, achieving chiral amplification. Furthermore, applications of CPL detection and biomedical applications are discussed.

Summary: This article reviews the historical research on circularly polarized light (CPL)-induced absolute asymmetric synthesis, including chiral organic molecules, helical polymers, supramolecular assemblies, and noble metal nanostructures. However, based on these results, it is concluded that the chiral photon-matter interaction is very weak, resulting in a very small enantiomeric excess for the product. Therefore, the recently emerged superchiral field technology, which can enhance the dissymmetry of the optical field and near-field, is highlighted.

Summary: We propose a widely applicable strategy to fill the spectral gap of circularly polarized light (CPL) detection in the near-infrared (NIR) region by directly inducing chiroptical activity in planar non-fullerene acceptors. This strategy is found to be effective in a wide series of state-of-the-art non-fullerene acceptor families, including ITIC5, o-IDTBR6, and Y6 analogues.

Summary: Using a new supramolecular organogel, helical nanoribbons with high helicity degree can be generated by irradiating with right- or left-circularly polarized light. The helical direction of the nanoribbons can be controlled by the direction of the circularly polarized light. This concept has potential applications in biology, pharmacology, and chiral optics.

Summary: This study proposes a strategy to achieve strongly dissymetric CPL in nanocomposite films based on chiroptical induction and energy transfer to semiconductor nanocrystals. By controlling the chirality of helical nanofilaments in liquid crystal matrix and adjusting energy transfer from organic films to quantum dots, CPL wavelengths can be conveniently tuned. This approach provides a simple and versatile method to modulate the CPL activity of organic materials.

Summary: The chirality of 2D chiral perovskite films has been significantly enhanced by a solvent modulation strategy, leading to the formation of CPL-active materials. By creating chiral perovskite/quantum dot composites, an increase in the CPL intensity was observed, attributed to the generation and transportation of spin-polarized charge carriers as well as the enlarged lattice distortion of the chiral perovskite films achieved through solvent modulation. This approach provides an effective way to construct CPL-active materials.

Summary: This study demonstrates that selective regulation on asymmetric photopolymerization can be achieved by the arbitrarily coupled irradiation with CPUV and CPVL, either constructively amplifying chirality or destructively changing the helical preference of polymer chains. The work highlights the importance of the chiral induction effect in the helical chain propagation process and provides a deeper understanding of the helical preference in CPL-triggered asymmetric photopolymerization.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
