Abstract
A series of oligomers analogous to poly(p-phenylenevinylene) (PPV), combini ng naphthalene and benzene as aromatic units, have been synthesized by a Kn oevenagel reaction. By measuring UV/Vis spectra, photoluminescence (PL) and electroluminescence (EL), we studied the influence of the position of the naphthalene unit as well as the steric and electronic influences of cyano a nd alkyloxy substituents on the luminescent properties of these compounds.
