Summary: Two fluorescent dyes, OTT-2 and OTK-2, were synthesized by oxidative homocoupling and Stille coupling reactions, respectively. OTT-2 exhibits stronger fluorescence properties and higher fluorescence quantum yield compared to OTK-2. The difference in their lowest unoccupied molecular orbital energy levels and highest occupied molecular orbital structures results in the variation of their optical properties.

Summary: This study focuses on the evaluation of MOFs based on TTF-tetrabenzoate as cathode active materials for rechargeable lithium-ion and sodium-ion batteries. The results show that MOF formation improves cycle stability and battery capacity at high current densities, indicating the potential for achieving improved charging/discharging rates. Additionally, MOFs based on H4TTFTB exhibit better battery performance in sodium-ion batteries compared to lithium-ion batteries. These findings suggest that using redox-active and rigid H4TTFTB as the ligand for MOFs is an effective method for high-performance energy storage devices.

Summary: The study reveals that water molecules adsorbed on highly biocompatible and poorly biocompatible acrylate-based polymers have different vibrational lifetimes, with PMEA showing stronger H-bonding interaction with water and PPEA exhibiting notably longer OD stretch vibrational lifetime. The results also demonstrate substantial spatial overlap between polymer CO group and water for hydrated PMEA, as well as a significant difference in surface morphology compared to PPEA, highlighting the underlying relationships among polymer-water interaction, surface morphology, and biocompatibility.

Summary: A bistable pseudorotaxane and rotaxane were synthesized to measure the height of an electrostatic barrier produced by double molecular oxidation. The study found that substituents on the MPTTF unit had profound effects on the physical properties of the systems and allowed for the first measurement of the deslipping of the CBPQT ring in the pseudorotaxane.

The addition of bromine atoms in the photosensitizers increased the singlet oxygen quantum yield. The photosensitizers exhibited low cytotoxicity in the dark and high phototoxicity under light conditions.

Summary: Redox-responsive compounds, including Tetrathiafulvalene (TTF) derivatives, have been widely studied in molecular nanotechnology for their potential applications in constructing redox-active materials. However, the use of BPTTF as a building block is still limited despite its favorable properties. This study reports the synthesis and functionalization of two novel non-symmetric BPTTF building blocks, which can be obtained from specific intermediates in moderate to high yields.

Summary: Infrared photothermal microscopy is a non-invasive and label-free imaging technique that has been used in various research areas. However, the narrow spectral width of the preferred excitation light source limits the molecular information obtained. Here, we introduce a two-color IR photothermal microscopy technique that overcomes this limitation and allows for the imaging and differentiation of two chemical species in live cells.

Summary: Controlling the movement of CBPQT(4+) ring is essential for the full potential utilization of artificial molecular machines. In this study, two isomeric tri-stable [2]rotaxanes incorporating TTF and MPTTF units were synthesized to measure the energy barriers during the movement of CBPQT(4+) ring. By strategically exchanging thiomethyl barriers with thioethyl groups, the movement of CBPQT(4+) ring in the synthesized compounds can be controlled to occur in only one direction. Cyclic voltammetry and H-1 NMR spectroscopy were used to investigate the switching mechanism. The results demonstrate the first successful induction of directional movement of CBPQT(4+) ring in molecular machines using a combination of TTF and MPTTF units with 90% efficiency.

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.
