group of the conjugated monomer. The hyperbranched
polymers exhibit a good solubility and processabil-
ity, a high glass transition temperature, and a high
fluorescence.
A high yield and stereospecific synthesis of seg-
mented PPV via the Heck reaction have been reported
[74]. Phosphite ligands and two different sources of
palladium were used.
