Thermoconversion method

Jang et al. [131] reported high electron affinity perfluorobiphenyl-substituted PPV 78. This polymer was synthesized by the thermoconversion method. Single-layer PLED ITO/ 78/Al showed 64 times higher EL efficiency than that fabricated with unsubstituted PPV 1. A further (380-fold) increase of efficiency was achieved in a bilayer device ITO/1/78/A1. [Pg.73]

The first realization of this approach was reported by the Cambridge group, which synthesized copolymers 80 containing phenylene vinylene and dialkoxy(phenylene vinylene) units by the thermoconversion method [23,134], A 30-fold improvement in EL efficiency was observed for these copolymers compared with PPV 1 or MEH-PPV 13 devices fabricated in the same configuration (Chart 2.15). [Pg.73]
