摘要

Oligo(1,5-dialkoxynaphthalene-2,6-diyl)s were synthesized by Ni(cod)(2) (cod=1,5-cyclooctadiene)-promoted condensation reactions of 1,5-dialkoxy-2,6-dibromonaphthalenes. The UVVis, photoluminescence (PL), and powder X-ray diffraction (XRD) measurements suggested that the oligomers have a self-assembling ordered structure in the solid state. The oligomers underwent electrochemical oxidation (p-doping), which occurred at lower potentials for films than for acetonitrile solutions containing [Et4N]BF4. This effect is caused by the longer pi-conjugation lengths of the oligomers in films, which was attributed to molecular self-assembly leading to ordered structures in the solid state. The electrochemical reaction of the oligomers was accompanied by electrochromism. (C) 2014 Wiley Periodicals, Inc.
