Cyanopolyyne

From Wikipedia, the free encyclopedia

A cyanopolyyne is an organic compound that contains a chain of one or more carbon-carbon triple bonds alternating with single bonds and ending with a cyanide functional group. The simplest example is cyanoacetylene, H−C≡C−C≡N.

Cyanopolyynes are relatively common in interstellar clouds, where they were first detected around 1970. Members up to HC
9N were detected in the Taurus Molecular Cloud 1, where they are believed to be formed by reaction of atomic nitrogen with hydrocarbons.[1] For a while, HC
11N held the record as the largest molecule detected in interstellar space, but its identification was challenged.[2][3]

Cyanoacetylene is one of the molecules that was produced in the Miller-Urey experiment.
