A series of cyclic tetraaryl[5]cumulenes has been synthesized. In the smallest of the cycles, the bond angles of the cumulene are distorted to as little as 172–174° based on crystallographic and computational analyses. Spectroscopic and physical properties as a function of ring size show small but consistent trends as ring strain increases.
