1. Chemical parlance knows the “bay” region in phenanthrene, which has three sides, and the “fjord” region (four sides) in benzo[c]phenanthrene. There does not seem to exist a catchy term for the inner region in [5]helicene (five sides) or in the related compounds 1 or 9,9′-bifluorenylidene of this paper. We suggest to call it a “cove”, which is “a circular or round inlet with a narrow entrance” (http://en.wikipedia.org/wiki/Cove as of March 18, 2005). This term would be most apt if the compounds in question were planar.
