Summary: Squaraine Figure Eight (SF8) dyes are deep-red fluorescent dyes with unique self-threaded molecular architecture, providing structural rigidity and protection for the fluorochrome. Studies have shown that SF8 dyes have significantly higher photostability and improved emission quantum yields, longer times to photobleaching, and enhanced total photon yields at the single molecule level compared to conventional dyes. SF8-based dye SF8(D4)2 exhibits three-fold larger emission quantum yield, order of magnitude longer average times before photobleaching, and twenty times larger photon yields compared to Cy5. These features, along with water solubility, fluorochrome encapsulation, and biomarker targeting capability, make SF8-based dyes promising for biological labeling, microscopy, and single molecule tracking applications.

Summary: This study reports a novel class of symmetric and asymmetric NH2-substituted core-NDIs with tunable fluorescence, where the bis-NH2-substituted NDI 2 shows high fluorescence quantum yield; the first NDI-based green-light emitter is demonstrated; and a method to modulate the excited-state intramolecular proton transfer process is proposed. The synthetic protocol simplifies the integration of -NH2 groups, and TD-DFT calculations predict strong intramolecular hydrogen bonds and responsiveness to solvent polarity in NDI fluorescence properties.

Summary: Novel far-red sensitive symmetrical squaraine dyes with alkyl chain terminal modification for multiple functionalities are designed. Iodine terminal modification enhances dye aggregation and binding strength, while imidazole terminal modification shows the opposite effect. The newly designed dyes demonstrate efficient photo sensitization and photon harvesting in dye-sensitized solar cells.

Summary: The study proposes a self-powered and highly sensitive tribo-label-sensor (TLS) by embedding triboelectric nanogenerator into the roller structure of a label printer. It delivers 6 times higher signal magnitude than traditional infrared sensor and is immune to label jitter and temperature variation. TLS can be used for transparent label directly and shows long-term robustness. This work provides an alternative toolkit to improve label printers and further promote the development of IoT.

Summary: Alkoxylation chemistry is introduced as a solution for exploring a new family of highly-fluorescent octupolar 2D-conjugated organic polymers/frameworks, combining far-red emission, high fluorescence quantum yield, and strong two-photon absorption. The alkoxy-substituted polymers display significantly redshifted emission, high quantum yields, and large two-photon absorption cross sections, making them suitable for applications in warm white light-emitting diodes and bio-imaging.

Summary: In this article, a novel catalytic reaction using Pd(0) and Bronsted acid is reported for the synthesis of biologically important imidazolidinone-fused N-heterocycles through redox-neutral intramolecular N-allylation of indoles and pyrroles with alkynes. This atom-economical method is applicable to a wide range of substrates and eliminates the need for leaving groups or oxidizing agents commonly used in traditional allylation reactions.

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.
