Reversible luminescent reaction of amines with copper(i) cyanide
Copper(i) cyanide exposed to various liquid or vapor-phase amines (L) at ambient temperature produces a variety of visible photoluminescence colors via reversible formation of amine adducts. The adducts show phase matches to authentic (CuCN)Ln, n = 0.75-2.0, produced by heating CuCN with liquid amine. © 2010 The Royal Society of Chemistry.
