AI Article Synopsis
- - A new polymerization method called rhodium-catalyzed stitching polymerization has been created to synthesize π-conjugated polymers, using nonconjugated 1,5-hexadiynes as monomers.
- - This polymerization technique is efficient, operates under mild conditions, and can also work with other similar monomers like 1,5,9-decatriyne and 1,5,9,13-tetradecatetrayne.
- - The method is advantageous because it allows the creation of difficult-to-make repeating units without needing a preformed bridged π-conjugated monomer.
Article Abstract
A new mode of polymerization, rhodium-catalyzed stitching polymerization, has been developed for the synthesis of π-conjugated polymers with bridged repeating units from nonconjugated 1,5-hexadiynes containing both terminal and internal alkyne moieties as monomers. The polymerization proceeded smoothly with a high degree of stitching efficiency under mild conditions, and 1,5,9-decatriyne and 1,5,9,13-tetradecatetrayne monomers could also be employed. The present polymerization strategy would be particularly beneficial for the synthesis of polymers consisting of a repeating unit that is difficult to prepare as a stable monomer because it does not require the use of a preformed bridged π-conjugated monomer.
