Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Molecular engineering towards tunable morphology of metal-organic complex microcrystals for efficient and multicolor electrochemiluminescence.Application In Synthesis of 5,5′-Dimethyl-2,2′-bipyridine.

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.

Author is Assuncao, Israel P.; Bredol, Michael; Kasprzycka, Ewa; Kynast, Ulrich H.; Lezhnina, Marina.

While numerous Eu3+ complexes are known now that can efficiently be exploited at 350-400 nm excitation range, corresponding green Tb3+ emitter complexes are hard to find. Tb3+ salts of fenamic acid and derivatives thereof are interesting candidates for applications using near-UV excitation: on addnl. co-coordination with e.g. 5,5′-dimethyl-2,2′-bipyridine, excitation maximum at 380 nm, at the same time maintaining high efficiencies, can be accomplished. Such coordination compounds hold the promise of being useful as versatile marker mols. in a variety of soft chem. environments.

Compound: 5,5′-Dimethyl-2,2′-bipyridine(SMILESS: CC1=CN=C(C=C1)C1=NC=C(C)C=C1,cas:1762-34-1) is researched.Application In Synthesis of 6-Chloropyridine-2-boronic Acid. The article 《Dimeric imidazolium ionic liquids connected by bipyridiyl as a corrosion inhibitor for N80 carbon steel in HCl》 in relation to this compound, is published in Journal of Molecular Liquids. Let’s take a look at the latest research on this compound (cas:1762-34-1).

A new type of the dimeric imidazolium-type amphiphile, BDBCmIB (m = 1, 4 and 8), was synthesized using the bipyridiyl as the spacer, and its inhibition performance and mechanism for the corrosion of N80 carbon steel in 1.0 mol·L-1 HCl were evaluated using chem. and electrochem. measurements, surface analyses and d. functional theory (DFT) calculations Results show that the inhibition efficiency of BDBCmIBs increases with their concentrations and the length of tail chains. BDBC8IB exhibits the best inhibition performance among them and its inhibition efficiency almost exceeds 90% in a wide concentration range from 1.0 × 10-6 to 5.0 × 10-4 mol·L-1 at 25.0 °C, which attains the maximum over 95% at 5.0 × 10-4 mol·L-1. Moreover, three BDBCmIBs all display the high inhibition efficiency at 5.0 × 10-4 mol·L-1, nearly exceeding 90%, in the temperature range from 25.0 to 55.0 °C. As a mixed-type inhibitor, BDBCmIBs can retard both cathodic hydrogen evolution and anodic metal dissolution processes, since BDBCmIB mols. bear the imidazolium-based heterocycle with the electron-donating ability and the bipyridine with the electron-accepting ability, thereby facilitating the formation of a protective film on the surface of N80 carbon steel via electrostatic interactions, coordinated and back-donating bonds. The adsorption of BDBCmIBs obeys the Langmuir isothermal model. Our finding demonstrates that the introduction of the bipyridiyl at the spacer does favor improving the inhibition efficiency of such dimeric imidazolium-type amphiphiles, and meanwhile, the proper increase in the number of carbon atoms in the substituents on the imidazole rings can also enhance the inhibition efficiency.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Reversible H2 oxidation and evolution by hydrogenase embedded in a redox polymer film, published in 2021-03-31, which mentions a compound: 1762-34-1, mainly applied to reversible hydrogen oxidation hydrogenase redox polymer film, Reference of 5,5′-Dimethyl-2,2′-bipyridine.

Efficient electrocatalytic energy conversion requires devices to function reversibly, i.e., to deliver a substantial current at a minimal overpotential. Redox-active films can effectively embed and stabilize mol. electrocatalysts, but mediated electron transfer through the film typically makes the catalytic response irreversible. Here we describe a redox-active film for bidirectional (oxidation or reduction) and reversible hydrogen conversion, which consists of [FeFe] hydrogenase embedded in a low-potential, 2,2′-viologen-modified hydrogel. When this catalytic film served as the anode material in a H2/O2 biofuel cell, an open circuit voltage of 1.16 V was obtained-a benchmark value near the thermodn. limit. The same film also acted as a highly energy efficient cathode material for H2 evolution. We explained the catalytic properties using a kinetic model, which shows that reversibility can be achieved even though intermol. electron transfer is slower than catalysis. This understanding of reversibility simplifies the design principles of highly efficient and stable bioelectrocatalytic films, advancing their implementation in energy conversion.

From this literature《Reversible H2 oxidation and evolution by hydrogenase embedded in a redox polymer film》,we know some information about this compound(1762-34-1)Reference of 5,5′-Dimethyl-2,2′-bipyridine, but this is not all information, there are many literatures related to this compound(1762-34-1).
