“…It is believed that during thermal treatment up to 400 °C, some cross link ing is induced through the quinoxaline rings. 39 The light emitting ability of poly(phenylquinoxalines) 19a-d containing silicon and imide rings was estimated on the basis of photoluminescence spectra recorded for polymer solutions in N methylpyrrolidone or for spin coated films after irradiation with UV light. 25, 28 The UV absorption spectra of these polymers in solutions showed maxima in the range of 363-374 nm, their behaviors being rather similar, although an aromatic radical (Ar) with a different extent of conjugation had been intro duced between the two phenylquinoxaline units (Table 4).…”

The synthesis and properties of poly(phenylquinoxalines) containing hexafluoroiso propylidene or silylene units in the backbone are described. The polymers have been prepared by polycondensation of aromatic diamines containing preformed phenylquinoxaline rings with a dianhydride or diacid chlorides containing hexafluoroisopropylidene groups, or with a dianhydride or diacid chlorides containing silylene units. The solubility, thermal stability, film forming ability, and electric insulating, mechanical, and electroluminescent properties of the thin films are discussed and compared with those of related heterocyclic polymers. Potential applications of poly(phenylquinoxalines) are outlined.
