We have succeeded in catenating two sterically encumbered 1,3‐di‐t‐butyl‐2,4‐bis(2,4,6‐tri‐t‐butylphenyl)‐1,3‐diphosphacyclobutane‐2,4‐diyl units with a spacer 1,2‐(CH2)2C6H4 to obtain bis(biradicals) as considerably stable compounds. We have discussed physicochemical properties of the dimer, together with DFT calculations of model compounds. Spectroscopic data, redox properties, and X‐ray structures of the oligo(biradicals) derivatives including other spacers like 1,3‐(CH2)2C6H4, 1,4‐(CH2)2C6H4, and 1,3,5‐(CH2)3C6H3, reveal that the P‐heterocyclic biradical moieties interact through nonconjugative pathways. These properties of oligo(biradicals) will facilitate to design novel molecular systems for electronics. © 2010 Wiley Periodicals, Inc.
