Interlocked polyynes towards stable carbynes

Nature Chemistry volume 16, pages 154–156 (2024)Cite this article

Subjects

Interlocking unstable motifs is a useful way to enhance their stability through shielding protection. Now, stable interlocked polyynes bearing several macrocycles have been prepared, including a [5]rotaxane having 34 contiguous alkynes with properties similar to those of carbyne.
