Cyclic polyynes have been proposed as theoretical compounds to illustrate the “particle on a ring” model discussed in many quantum chemistry courses. I've looked it up on Wikipedia but there it's not clear whether one has ever been synthesised, or not.

So: have cyclic polyynes been synthesised? If not, what is the difficulty in achieving this?
