Poly(Biradicals): Oligomers of 1,3‐Diphosphacyclobutane‐2,4‐diyl Units

Abstract

Biradical chromophore bridge: Di- and trimethylenephenyl moieties facilitate a through-space interaction between sterically demanding biradical subunits (see picture), enabling the design of new electronic materials. The solid-state structure of a bis(biradical) derivative illustrates the proximal positioning of two biradical subunits, allowing for direct interaction between them.
