Sulfinfinitenes: infinitenes of fused thiophene rings

Abstract

Sulfinfinitenes, analogues of infinitene constructed from thiophene rings and assembled by applying a “cut–twist–restitch” sequence to two sulflowers, are explored through DFT calculations. The sulfinfinitene with 16 thiophene rings is only slightly more strained than the [8]sulflower, which has been synthesized, and can be considered as a promising synthetic target.
