Description:

We explored the appropriate monomer structures and reaction conditions for the site- and regio-selective hydroarylation polyaddition of PAHs using a Co-catalyst. As poly(naphthalene) and poly(naphthalenevinylene) derivatives linked at β-positions show high fluorescence quantum yields (Φ > 0.7) and have been applied to OLEDs, 2,6-di(1-pyrazolyl)naphthalene was designed as a new naphthalene monomer. A site- and regio-selective hydroarylation polyaddition proceeded smoothly under mild reaction conditions to obtain the corresponding PAV. In addition, this monomer design was applicable to the hydroarylation polyaddition of a carbazole unit. Furthermore, the optical and electronic properties of the synthesized PAVs were evaluated.
