In chemistry, a polyyne /ˈpɒlɪʌɪn/ is any organic compound with alternating single and triple bonds; that is, a series of consecutive alkynes, (−C≡C−)
n with n greater than 1. The simplest example is diacetylene or buta-1,3-diyne, H−C≡C−C≡C−H.
These compounds have also been called oligoynes, or carbinoids after "carbyne" (−C≡C−)
∞, the hypothetical allotrope of carbon that would be the ultimate member of the series. The synthesis of this substance has been claimed several times since the 1960s, but those reports have been disputed. Indeed, the substances identified as short chains of "carbyne" in many early organic synthesis attempts would be called polyynes today.
Polyynes are distinct from polyacetylenes, polymers formally obtained by polymerization of acetylenes. The backbones of polyacetylenes have alternating single and double bonds n. In biochemistry and plant biology, "polyacetylene" is routinely used to describe naturally occurring polyynes and related species.
Along with cumulenes, polyynes are distinguished from other organic chains by their rigidity, which makes them promising for molecular nanotechnology. Polyynes have been detected in interstellar molecular clouds where hydrogen is scarce.
I'm counting up the tolls
That I have paid for living my life
I'm patchin up the holes
Being gouged by this mass condemnation
But I won't be responsible for the things they've said and done
And I won't be responsible for any battles lost or won
Every person in this world can drop dead except for you
Every person in this world is on their side but you
And wherever you may go
I will go
I've come in from the cold
And I'm so glad that I've found my home
I'm keepin all I hold
It's not often that you get the things you've asked for
But you can't be responsible for the things they'll take away
I won't be opposable
Don't want to fight for every day
The questions you ask me have answers
Plain and clear
I will go and leave forever on the day
They find the boy who loves you half as much as I do
And until that day I will remain and never go away
But I can't be responsible for all the things they've done to you
They won't be held accountable and there's nothing you can do
They depend on the truth
Every person in this world can drop dead except for you
Every person in this world is on their side but you
And wherever you may go
