Summary: In this study, photoswitchable fluorescent supramolecular metallacycles with high fatigue-resistance were constructed by coordination-driven self-assembly using bithienylethene with dipyridyl units as a coordination donor and a fluorescent di-platinum(II) as a coordination acceptor. The reversible transformation between ring-open and ring-closed forms, along with the exceptional photostability of the metallacycles, suggests their potential promising applications in optical switching, image storage, and super-resolution microscopy.

Summary: DNA nanotechnology has potential for fluorescent biosensors in bioimaging, but uncontrollable target identification and molecular collision of nucleic acids may affect imaging precision and sensitivity. To address these challenges, innovative approaches are integrated, such as incorporating a photocleavage bond and using core-shell upconversion nanoparticles as an ultraviolet light source for near-infrared photocontrolled sensing. Additionally, a DNA linker is employed to confine the collision of nucleic acid reactants, leading to enhanced local reaction concentrations and highly sensitive detection. The developed fluorescent nanosensor shows excellent assay performance and bioimaging competence in live biosystems, advancing the field of DNA nanotechnology in biosensing.

Summary: Bis-and tris-pyridyl borate ligands with pyridyl donor arms, a methylated boron cap, and a fluorine-lined coordination pocket have been synthesized and used in coinage metal chemistry. These ligands allowed for the isolation of group 11 metal-ethylene complexes, with gold complexes showing the largest coordination-induced upfield shifts of the ethylene 13C resonance. Solid-state structures of these complexes revealed the rare K2 coordination mode instead of the typical K3 coordination mode. Computational analyses indicated the favored K2 coordination mode and the strong interaction between gold(I) and ethylene.

Summary: The fluorescence imaging technique is widely used in natural and life sciences, but current commercial biomarkers have several disadvantages. In this study, two new fluorescent molecular rotors (SB-B2 and SB-B23) derived from Boron Schiff bases (BOSCHIBAs) were synthesized and characterized. The crystal structure of SB-B23 showed a binuclear complex. Both compounds exhibited viscochromic and thermochromic properties. These low cytotoxicity BOSCHIBAs showed selective fluorescent staining of the endoplasmic reticulum in HeLa cells and HUVECs.

Summary: This report describes the stabilization of Cu(I) and Ag(I) pi-acetylene complexes supported by fluorinated and non-fluorinated, pyrazole-based chelators. These complexes were formed easily in solutions and could be isolated as crystalline solids. Different coordination modes and metal centers were observed, and the coordination shifts of acetylenic carbon resonance were revealed by C-13 NMR spectroscopy. The bonding between the transition metal fragment and the acetylene ligand was found to be stronger in the copper complexes. The C C distance of these complexes was shorter than expected due to incomplete deconvolution of thermal smearing and electron density anisotropy in acetylene.
