Electrochemiluminescence (ECL) of crystalline materials has recently attracted increasing attention due to their unique characteristics and applications, such as crystallization-induced emission, active waveguiding, and biosensing. Tris(2,2′-bipyridine)ruthenium(II), [Ru(bpy)3]2+, a classical metal-organic complex for ECL studies, has been fully investigated in solution as well as its derivatives However, the dependence of ECL properties on the mol. structure and crystal morphol. of these complexes has not been illustrated, partially due to the difficulty in the controlled crystal growth. Here, we adopt a facile mol. engineering strategy to obtain microcrystals of [Ru(bpy)3]2+ derivatives with well-defined morphol. (rods, wires, or polyhedrons) and varied phosphorescence emission colors (yellow, orange, and red) by simply changing the position and number of Me substituents on the bipyridine ligands. The packing modes of mols. influenced by Me groups play a vital role in crystal growth based on attachment energy anal. The obtained microcrystals could act as ECL luminophores when modified on glassy carbon electrode surfaces. Those with one-dimensional (1D) morphol. generally show superior ECL efficiency and stability to three-dimensional (3D) shaped microcrystals. ECL biosensors made of stable 1D microcrystals show reliable and sensitive responses to hydroxyproline, demonstrating their capacity in recyclable detections. This work demonstrates the great potential of mol. engineering in controlling the morphol., emission colors, and ECL properties of mol. crystals, paving the way for the development of high-performance ECL biosensing and optoelectronic devices.

The facile construction of metal-DNA complexes using ‘Click’ reactions is reported here. A series of 2′-propargyl-modified DNA oligonucleotides were initially synthesized as structure scaffolds and were then modified through ‘Click’ reaction to incorporate a bipyridine ligand equipped with an azido group. These metal chelating ligands can be placed in the DNA context in site-specific fashion to provide versatile templates for binding various metal ions, which are exchangeable using a simple EDTA washing-and-filtration step. The constructed metal-DNA complexes were found to be thermally stable. Their structures were explored by solving a crystal structure of a propargyl-modified DNA duplex and installing the bipyridine ligands by mol. modeling and simulation. These metal-DNA complexes could have wide applications as novel organometallic catalysts, artificial RNases, and potential metal delivery systems.

Cross-electrophile C-Si coupling has emerged as a promising tool for the construction of organosilanes, but the potential of this method remains largely unexplored. Herein, we report a C(sp3)-Si coupling of unactivated alkyl bromides with vinyl chlorosilanes. The reaction proceeds under mild conditions, and it offers a new approach to alkylsilanes. Functionalities such as Grignard-sensitive groups (e.g., acid, amide, alc., ketone, and ester), acid-sensitive groups (e.g., ketal and THP protection), alkyl fluoride and chloride, aryl bromide, alkyl tosylate and mesylate, silyl ether, and amine were tolerated.

2,2′-Bipyridyls have been utilized as indispensable ligands in metal-catalyzed reactions. The most streamlined approach for the synthesis of 2,2′-bipyridyls is the dehydrogenative dimerization of unfunctionalized pyridine. Herein, we report on the palladium-catalyzed dehydrogenative synthesis of 2,2′-bipyridyl derivatives The Pd catalysis effectively works with an AgI salt as the oxidant in the presence of pivalic acid. A variety of pyridines regioselectively react at the C2-positions. This dimerization method is applicable for challenging substrates such as sterically hindered 3-substituted pyridines, where the pyridines regioselectively react at the C2-position. This reaction enables the concise synthesis of twisted 3,3′-disubstituted-2,2′-bipyridyls as an underdeveloped class of ligands.

The binuclear complexes 1-2 are isomorphous and crystallize in the triclinic crystal system and P1̅ space group, and each metal center is eight-coordinated with distorted square antiprismatic mol. geometry. The structure of this type of complex is unique in that the solvent ethanol mol. participates in the coordination. Complexes 1-2 are stitched together via π-π stacking interactions and hydrogen bonding interactions to form the 1D, 2D supramol. structures. The thermal decomposition mechanisms of two complexes were obtained by TG-DSC/FTIR techniques. The molar heat capacities of the complexes 1 and 2 are measured by a DSC instrument over the temperature range from 255.15 to 323.15 K and thermodn. functions were calculated by fitted polynomial and thermodn. equations.
