Tetrahydrofuran is a heterocyclic organic compound with the molecular formula C4H8O. Tetrahydrofuran belongs to ethers and is the complete hydrogenation product of furan. It is a colorless, water-miscible organic liquid with small viscosity at normal temperature and pressure. Because of its long liquid range, it is a commonly used medium polar aprotic solvent. Its main use is as a precursor of high molecular polymers.
The ADC linker is one of the three main components of antibody drug conjugates (ADCs), linking the antibody to the effective drug (payload) through chemical bonds. ADC linkers play a key role in determining the overall success of antibody drug conjugates. One of the major challenges in developing safe and effective ADC drugs is to assemble an ideal chemical linker between the cytotoxic payload and the mAb. Well-designed ADC linkers can help the selective delivery of antibodies at the tumor site and the accurate release of cytotoxic drugs.
Solar Cell Materials refers to the materials used in the construction and functioning of solar cells. These materials play a crucial role in converting sunlight into electrical energy through the photovoltaic effect. Some common solar cell materials include: perovskite-based solar cells (PSCs) materials, dye-sensitized solar cells (DSSCs) materials, organic photovoltaic (OPV) materials. It's important to note that ongoing research and development in solar cell materials aim to improve efficiency, reduce costs, and explore new alternatives for sustainable energy generation.
Furan is a cyclic flammable liquid compound C4H4O that is obtained from wood oils of pines or made synthetically and is used especially in organic synthesis. Furan is aromatic because a pair of lone pair electrons of the oxygen atom in its molecule forms a large π bond in the plane of the conjugated orbital, making a total of 6 electrons in the plane of the conjugated plane, conforming to the 4n+2 structure. Aromaticity makes furan have the property of easy substitution and difficult addition. The other lone pair of electrons in oxygen stretches out. The oxygen atom itself conforms to sp2 hybridization. Due to the presence of the aromatic ring, the chemical behavior of furan is not very similar to that of other unsaturated heterocycles. The oxygen in the aromatic ring has an electron-donating effect, so the electrophilic substitution reactivity of furan is stronger than that of benzene.
