Lang, Christiane, Voll, Dominik, Inglis, Andrew J., Dingenouts, Nico, Goldmann, Anja S., Barner, Leonie, & Barner-Kowollik, Christopher (2011) An access route to polyferrocenes via modular conjugation. Macromolecular Chemistry and Physics, 212(8), pp. 831-839.
The application of copper-catalyzed azide/alkyne cycloaddition to monomers containing a ferrocene unit leads to polyferrocenes with ferrocene in the backbone. Catalyst performance and kinetic studies of a model system comprising 1,1'-bis(azidoethyl)ferrocene and propargyl ether revealed the usage of CuI and DBU as the catalyst in DMF at 50 °C as efficient reaction conditions for the synthesis. The resulting polymers display molecular weight-averages up to = 10 000 and = 33 000. The polyaddition of monomers both containing ferrocene units led to polyferrocenes with between 4 000 and 11 000 ( up to 78 000). The present study thus provides a pathway to polyferrocenes based on modular ligation chemistry.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
