2-Ethynylpyridine is a chemical compound commonly employed as a versatile building block in organic synthesis. Its molecular structure consists of a pyridine ring with an ethynyl group (-C≡CH) attached to the 2-position, making it highly reactive and suitable for various reactions leading to the formation of diverse organic compounds.

One significant application of 2-ethynylpyridine is in the synthesis of conjugated polymers. Through polymerization reactions, 2-ethynylpyridine can be polymerized to form polymers with unique properties. For example, it can be polymerized to yield poly(2-ethynyl-N-iodopyridinium iodide), poly[2-ethynyl-N-(2-furoyl)pyridinium chloride, and poly[2-ethynyl-N-(propylsulfonate)pyridinium betaine]. These polymers exhibit different functionalities and can find applications in areas such as optoelectronics, materials science, and biomedical engineering.

Additionally, 2-ethynylpyridine can react with various reagents to produce functionalized derivatives. For instance, its reaction with anionic heptaphosphide clusters yields the 4-(2′-pyridyl)-1,2,3-triphospholide anion, which may have applications in coordination chemistry and catalysis.

Moreover, 2-ethynylpyridine can be incorporated into water-soluble ionic conjugated polymers, such as poly[N-(carboxymethyl)-2-ethynylpyridinium bromide], enabling their use in aqueous environments for applications in sensors, drug delivery, and biomedical research.

Furthermore, 2-ethynylpyridine can undergo self-doping reactions to form self-doped ionic conjugated polymers like poly(2-ethynylpyridinimum N-benzoylsulfonate), which possess enhanced conductivity and stability, making them suitable for electronic and optoelectronic applications.

In summary, 2-ethynylpyridine serves as a valuable building block in organic synthesis, enabling the preparation of conjugated polymers and functionalized derivatives with diverse properties and potential applications in various fields of science and technology.
