Synthesis of pyrrole-based poly(arylenevinylene)s via Rh-catalyzed dehydrogenative direct alkenylation

摘要

Polycondensation via Rh-catalyzed dehydrogenative direct alkenylation was conducted. The introduction of a directing group, such as a 2-pyrimidinyl substituent, to the pyrrole monomer promoted a polycondensation reaction, giving rise to corresponding poly(arylenevinylene)s with a trans-configuration in good yields. The absorption and electronic properties of the polymers were examined.
