“…In addition, it has been reported that aromatic polymers (e.g., PSt, poly(N-vinylcarbazole), and polyaniline) and TOQ readily form charge-transfer complexes. [17][18][19][20][21] Therefore, it was expected that dehydrogenation of PCHD with excess TOQ would result in the formation of a PPP-TOQ charge-transfer complex (Scheme 3). In order to confirm this, the preparation and dehydrogenation of PCHD were carried out as follows.…”

“…It was found that the order of reactivity was TOQ > 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) > TCQ; in other words, TOQ was the strongest electron acceptor among these quinones. In addition, it has been reported that aromatic polymers (e.g., PSt, poly( N -vinylcarbazole), and polyaniline) and TOQ readily form charge-transfer complexes. − Therefore, it was expected that dehydrogenation of PCHD with excess TOQ would result in the formation of a PPP-TOQ charge-transfer complex (Scheme ).

Soluble high molecular weight poly(p-phenylene) (PPP), in the form of a charge-transfer complex, was synthesized by complete dehydrogenation of poly(1,3-cyclohexadiene) (PCHD) with excess tetrachloro-1,2-(o)-benzoquinone (TOQ). The yield of the PPP-TOQ complex increased as the molecular weight of the original PCHD increased. The addition of TOQ to the PPP polymer chain occurred mainly at the 1,4-phenylene (Ph) units. The PPP-TOQ complex showed good solubility in tetrahydrofuran; the solubility was not limited by the length of the 1,4-Ph sequence. The formation of the PPP-TOQ complex effectively suppressed crystallization of PPP due to the decrease in π-π intermolecular interactions in the PPP molecules, and had a significant effect on π-orbital conjugation in PPP.

SHARMA and SIJD: Dielectric relaxation studies in undoped and doped poly(viny1 alcohol) filmsThe thermally stimulated discharge technique has been used to investigate the dielectric relaxation phenomena in undoped/doped films of poly(viny1 alcohol). The thermal current spectra indicate a single relaxation process. The activation energy, relaxation time and relaxation constant were calculated using the initial rise method. The effect of the impurity incorporation into the polymer on its thermal spectra is discussed. Untersuchungen der dielektrischen Relaxation in dotierten und undotierten Polyuinylalkohol-FilmenDie Methode der thermisch stimulierten Entladung wurde zur Untersuchung der dielektrischen Relaxation in dotierten und undotierten Polyvinylalkohol-Filmen eingesetzt. Die TSC-Spektren zeigen einen einfachen Relaxationsprozefi. Aktivierungsenergie, Relaxationszeit und Relaxationskonstante wurden mit Hilfe der Anfangsanstieg-Methode berechnet. Der EinfluS der dem Polymer zugesetzten Verunreinigungen auf die thermischen Spektren wird diskutiert.
