First synthesis of the bismole‐containing conjugated polymer

Abstract

We successfully synthesized the first conjugated polymer containing a bismuth atom in the conjugated main chain by incorporating a bismuth atom into the cyclopentadiene framework (bismole), which was constructed by a polymer reaction. A synthetic procedure and characterization of the obtained polymers were discussed. This bismole‐containing conjugated polymer exhibited moderate bluish green photoluminescence in solution. © 2006 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 44: 4857–4863, 2006

Functional Polymeric Materials Based on Main‐Group Elements

“…[176] Metallapolymer precursor approaches have also been used to incorporate phospholes,a rsoles,a nd bismoles into polymers.T omita, Naka et al's. [178] [177] In addition, Chujo et al demonstrated that iodination of az irconacycle-containing polymer followed by alithium-iodine exchange and treatment with PhBiBr 2 generates the respective bismole polymer.…”

“…Eine elegante Synthese von orange lumineszierenden Arsol-Polymeren 102 ausgehend von Titanacyclen nach Tomita, Naka et al ist in Schema 11 (unten) veranschaulicht [177]. Darüber hinaus zeigten Chujo et al,d ass die Iodierung eines Zirconacyclus-haltigen Polymers,g efolgt von einem Lithium-Iod-Austausch und der Umsetzung mit PhBiBr 2 ,das jeweilige Bismol-Polymer bildet [178]. 4.4.…”

The Dawn of Functional Organoarsenic Chemistry

“…However, investigations of “arsoles” from the viewpoint of materials science remain to be performed, although some arsole derivatives were synthesized up to the 1960s . If studies on pnictogen‐type heteroles are performed by experimental means, pyrrole, phosphole, stibole, and bismole derivatives are prepared, but their arsenic analogues tend to be excluded. Nevertheless, computational studies have constantly predicted the intrinsic natures of arsoles: frontier orbitals, inversion energies, and aromaticity .…”
