Abstract
[3]Radialenes: 4,5,6‐Tris(2,4,6‐tri‐tert‐butylphenyl)phospha[3]radialene has been synthesized (see picture). The compound can be easily handled in air under ambient conditions, despite the [3]radialene moiety containing PC bonds, and exhibits red‐shifted absorption as well as high electron‐accepting ability. The unique electronic properties are brought about by the synergistic effect of the [3]radialene framework and the phosphorus substitution.
