Nitriles used to be known as cyanides; the smallest organic nitrile is ethanenitrile, CH3CN, (old name: methyl cyanide or acetonitrile – and sometimes now called ethanonitrile). 3032-92-6, formula is C9H5N, Name is 4-Ethynylbenzonitrile. Nitriles are found in many useful compounds, including methyl cyanoacrylate, used in super glue, and nitrile rubber, a nitrile-containing polymer used in latex-free laboratory and medical gloves.

Sebris, Armands;Novosjolova, Irina;Traskovskis, Kaspars;Kokars, Valdis;Tetervenoka, Natalija;Vembris, Aivars;Turks, Maris research published 《 Photophysical and Electrical Properties of Highly Luminescent 2/6-Triazolyl-Substituted Push-Pull Purines》, the research content is summarized as follows. New push-pull N(9)-alkylated 6-piperidino-2-triazolylpurine and 2-piperidino-6-triazolylpurine derivatives are synthesized, and their optical and optoelectronic properties are comprehensively characterized with exptl. and computational methods. The compounds possess intense violet or blue fluorescence with fluorescence quantum yields of up to 91% in solution and 40% in host-free films. Depending on their structural composition, the compounds have ionization energy in the range of 5.25-6.04 eV, electron affinity of 2.18-3.15 eV, and triplet energy of 2.52-2.95 eV. Due to the presence of hole-transporting purine and electron-transporting triazole fragments, compounds exhibit bipolar charge-transportation ability. Despite the favorable emissive properties of the studied push-pull purines, their electroluminescence in thin films is quenched owing to large current densities that are present even at a moderate driving voltage. This marks application directions related to a predominantly charge-transportation functionality as the most suitable for this compound class.
Safety of 4-Ethynylbenzonitrile, 4-Ethynylbenzonitrile is a simple benzyl alkyne compound potentially useful as a synthetic fragment and as a test compound for cross-coupling protocols. 4-Ethynylbenzonitrile has been described as a model compound for studying hydrogen bond formation in multifunctional molecules, as it contains four hydrogen bonding sites of which three are π-acceptors.
4-Ethynylbenzonitrile is a useful research compound. Its molecular formula is C9H5N and its molecular weight is 127.14 g/mol. The purity is usually 95%., 3032-92-6.
