On April 1, 2008, Karastatiris, Panayiotis; Mikroyannidis, John A.; Spiliopoulos, Ioakim K. published an article.SDS of cas: 146370-51-6 The title of the article was Bipolar poly(p-phenylene vinylene)s bearing electron-donating triphenylamine or carbazole and electron-accepting quinoxaline moieties. And the article contained the following:
Two new poly(phenylenevinylene)s (PPVs) carrying electron-donating triphenylamine or carbazole and electron-deficient quinoxaline units were synthesized and characterized. Their properties were compared with those of PPV containing only quinoxaline unit. The two polymers showed PL maximum at 501-510 in solution and 533-540 in thin film. Because of the presence of electron donor and acceptor units they displayed strong intramol. charge transfer (ICT) effects; hence, low-photoluminescence (PL) quantum yields. The polymers showed reversible electrochem. reduction with electron affinity of 2.75 eV and irreversible oxidation with ionization potential of 5.10-5.24 eV. Single-layer LED of configuration ITO/PEDOT/polymer/Al showed low turn-on voltage at 5 V, but limited brightness of 50-60 cdm-2. The electroluminescence maximum was voltage-tunable varying from 500 to 542 nm. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).SDS of cas: 146370-51-6
