Autor: E. G. J. Staring, P. Urbach, A. J. M. Berntsen, S. T. R. Romme, G. L. J. A. Rikken
Publikováno v: Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences. 355:695-706
In this paper we describe a quantitative approach to the photochemical degradation of a soluble dialkoxy–PPV that was also used to make polymer light–emitting diodes. We have defined a quantum yield for degradation (γ) and investigated the depen

Publikováno v: Scopus-Elsevier
We have identified excited-state singlet oxygen as a reactive intermediate in the solid state photo-oxidation of two poly(p-phenylene vinylene) (PPV) derivatives, poly(2,5-bis(5,6- cholestanoxy)-1,4-phenylene vinylene) (BCHA-PPV) and poly(2-methoxy,5
