Polyfp-phenylene vinylene

ErQ3 gives both PL and EL emission at 1,500 nm.207-209 Red light (614 nm) is emitted by [Eu(TTFA)3(phen)] (Figure 2(a)) doped in a poly(A-vinylcarbazole) layer.210 The complex [Eu(TTFA)3(TPPO)2] (TPPO = triphenylphosphine oxide, see Figure 2(f)) emits in the red when incorporated in OLEDs,211,212 behavior which is enhanced when the material is heat treated.204 Near-IR EL and PL emission was observed from blends of polyfp-phenylene-vinylene) with [Yb(TPP)(ACAC)] and [Er(TPP)(ACAC)] (H2TPP is 5,10,15,20-tetraphenylporphyrin) by both EL and PL 213...
