Abstract

Partially metallated polymers of 2-vinylfluorene in tetrahydrofuran THF and THF-dimethoxyethane mixtures were studied by electronic absorption spectroscopy. Effects arising from interaction of the ion pairs within the polymer chain were clearly observed. Conversion of the contact ion pairs with lithium and sodium cations into the solvent-separated ion pairs is influenced by interactions between the solvent-separated ions pairs. The polymer carbanions with bulky K** plus and Cs** plus cations exhibited a shift of lambda //m//a//x with increasing carbanion concentration, suggesting the formation of an extended polymer chain in solution.
