In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Molecular engineering towards tunable morphology of metal-organic complex microcrystals for efficient and multicolor electrochemiluminescence, published in 2021, which mentions a compound: 1762-34-1, Name is 5,5′-Dimethyl-2,2′-bipyridine, Molecular C12H12N2, Formula: C12H12N2.
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.
