Abstract

Three new PPV derivatives with dialkoxyphenyl substituents, BEH2P-PPV, BEH3P-PPV, and BEH4P-PPV have been synthesized. The polymers were characterized by FT-IR, 1H NMR, and elemental analysis. The polymers possess excellent solubility, high molecular weights, high photoluminescence efficiencies and good thermal stability. The influence of substitution pattern on the formation of structural defects has been investigated by measuring the ...
