alkyne

[al′kīn]

alkyne (alˑ·kīnˈ),

n unsaturated hydrocarbon compound that has triple covalent bonds and CnH2n−2 as the general chemical formula. This functional group is not common in components of essential oils.

The reactions' gluing powers have also proven extremely effective at binding fluorescent alkyne dyes to proteins and other biological components, which allows researchers to observe how they behave in cells and what roles they may play in diseases.
Caption: Molecules with a diazonium group on one end and an alkyne group on another can serve as a 'primer' to build up ultra-thin layers of electronically active molecules.
An alternative to using an alkyne is to use norbornadiene which can be thought of as a masked alkyne (Barbara, 2003).
These polymers have gained a huge interest academically in recent years as the azide group can undergo a cycloaddition reaction with a terminal alkyne group in presence of a Cu(I) catalyst to make block, graft, brush, and star polymers.
The contributions describe approaches for conjugating proteins and peptides to polymers, generating complex macromolecular architectures via orthogonal and selective cycloadditions, fabricating alkyne and azide functionalized surfaces, and designing multifunctional network polymers.
