Polytriacetylenes: Conjugated polymers with a novel all-carbon backbone


  • This work was supported by the Swiss National Science Foundation and a grant from the ETH Research Council (F. D. and L. D.).


New, synthetically accessible, soluble, stable all-carbon-backbone polymers are reported. The polytriacetylenes (see Fig.) represent an intermediate step between polydiacetlylenes and carbyne and as such are of interest as alternatives for known conjugated polymers. The synthesis, film casting, and interesting properties are discussed.
