dc.description.abstract A reductive coupling reaction employing sodium bis(2-methoxyethoxy) aluminum hydride is used to prepare main chain azo-polymers comprising of polycyclic aromatic hydrocarbons (naphthalene, anthraquinone, or fluorenone) from their dinitro-derivatives. The azo-bridges act as effective means of conjugation and all polymers exhibit differences in the ultra-violet-visible light absorption and photoluminescence emission spectra depending on the degree of polymerization. Furthermore, in the case of poly(azofluorenone)s and poly(azoanthraquinone)s, these spectra may be modified by changes in the protonation state of the polymers. The lowest unoccupied molecular orbital and highest occupied molecular orbital energy levels and the band gap of poly(azoanthraquinone) are estimated from cyclic voltammetry data and UV-visible absorption of films. en
