Abstract

Abstract : The synthesis, characterization, and ring-opening metathesis polymerization of a norbornene-functionalized boron difluoride formazanate complex is reported. The spectroscopic and electrochemical properties of monomer/polymer are compared and discussed in detail. Abstract : The synthesis, characterization, and ring-opening metathesis polymerization (ROMP) of a novel norbornene-based boron difluoride (BF2 ) formazante monomer are described in detail. The polymerization studies confirmed ROMP to occur in the presence of BF2 formazanates, and also demonstrated the controlled nature of the polymerization. The polymers retained many of the unique characteristics of the monomers in dichloromethane, including absorption and emission at maximum wavelengths of 518 and 645 nm, large Stoke's shifts ( υ ST = 127 nm, 3800 cm −1 ), and the ability to act as electron reservoirs to form borataverdazyl-based poly(radical anions) ( ). Furthermore, the results described in this paper demonstrate the potential of these and related polymers based on BF2 formazanates as redox-active, light-harvesting materials.
