Summary: Controlling the localization/delocalization of radicals is crucial for functional materials. In this study, the authors synthesized and studied diruthenium (p-diethynylacene)diyl complexes and their monocationic radical species. They found that the energy gaps could be finely tuned by the acene rings in the bridging ligands, resulting in absorption maxima ranging from UV to NIR. The cationic species showed characteristic NIR bands attributed to charge resonance and pi-pi* transition bands, and the expansion of acene rings led to blue shifts of charge resonance bands and red shifts of pi-pi* transition bands.

Summary: Materials exhibiting multi-photon absorption (MPA), such as metal alkynyl complexes, have significant potential applications in microfabrication, bio-imaging and sensing, and photodynamic therapy. The collinear structure of metal and alkynyl ligand in these complexes promotes strong electron delocalization and intra-molecular charge transfer, leading to outstanding MPA behavior.

Summary: Multifunctional switches are crucial for the development of smart molecular materials and molecular-electronic applications. The synthesis, structure, and characterization of spiropyrans functionalized with alkynyl-[Ru(dppe)(2)] groups are described. The study demonstrates access to several stable redox states using electrochemical and spectroelectrochemical methods, as well as via acidochromism and photoisomerisation. The spiropyran also exhibits effective insulation properties for electronic communication across the molecular backbone.

Summary: We report on the synthesis and characterization of a new bis(alkenylruthenium) complex with a longitudinally extended, pi-conjugated dibenzotetrathiafulvalene bridge. The complex undergoes four consecutive oxidations and forms an electronically coupled mixed-valent state. It also reacts with strong organic acceptors to form a radical cation.

Summary: In this study, coordination polymers were used as triboelectric materials to expand the application range of triboelectric nanogenerators by utilizing the well-arranged and tunable frameworks of crystalline materials. The electronic structure contributions of different bridging ligands were determined and their effects on the output of TENGs were verified. Additionally, adjusting the concentration of Cd-CP in PVDF composite films effectively enhanced the output performance of TENGs.

Summary: This study introduces a novel synthetic route to prepare heterobimetallic compounds incorporating Pt(II) diyne and polyine with 5,5'- and 6,6'-disubstituted 2,2'-bipyridines. The incorporation of Re(CO)(3)Cl pendant functionality in these compounds has a synergistic effect on the optical properties, resulting in red shifting of absorption and strong long-wavelength absorptions. Computational modeling revealed that 5,5'-disubstituted 2,2'-bipyridine systems are better candidates due to higher yield, improved photophysical properties, and stability compared to their 6,6'-substituted counterparts.

Summary: In this study, three novel MOFs were assembled by the meta derivative of the commonly used p-H4TTFTB ligand, m-H4TTFTB, and lanthanide metal ions (Tb3+, Er3+, and Gd3+). These MOFs exhibited low porosity due to their dense stacking. Solid-state cyclic voltammetry studies showed similar redox activity in these MOFs. The magnetic properties suggested slow relaxation of the magnetization in Dy-m-TTFTB and Er-m-TTFTB. Although these materials lacked porosity, the m-TTFTB ligand showed promise for constructing redox-active or electrically conductive MOFs in future work.

Summary: In this study, a mixed-linker conductive MOF system was developed by incorporating tetrathiafulvalene and Ni-bis(dithiolene) moieties, allowing precise control over electronic structures and semiconductor characteristics by adjusting their molar ratio. The semiconducting behavior of the MOF system can be switched from n-type to p-type by increasing the ratio of tetrathiafulvalene to Ni-bis(dithiolene), resulting in a three orders of magnitude increase in electrical conductivity. Additionally, the mixed-linker MOFs showed synergistic and nonlinear modulation effects on the chemiresistive detection of VOCs, with sensing performance modulated by the linker ratios.

Summary: In this work, oxidatively doped tetrathiafulvalene (TTF)-based metal-organic frameworks (MOFs) were used as high-performance electrodes in supercapatteries. These MOFs exhibited significantly increased electrical conductivity and high specific capacities. When used as positrodes in a supercapattery, they showed great energy density and cycling stability. The results indicate that constructing unique dense and robust structures of MOFs followed by postsynthetic oxidative doping is an effective approach for fabricating MOF-based electrode materials.

Summary: Surface modification of electrodes with glycans was explored as a strategy to modulate the development of electrocatalytic biofilms in microbial fuel cell applications. The presence of different types of glycans on electrodes significantly impacted the performance of microbial fuel cell devices, with lactosides inhibiting biofilm development and mannosides promoting biofilm adhesion. This study demonstrates the potential of leveraging specific glycan-mediated bioaffinity interactions to direct the development of biotic electrocatalysts in bioelectrochemical systems.

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.
