Poly Phenylene Ethynylene s

An interesting example of extremely long monodisperse phenylene ethynylene wires  [Pg.225]

The EL of poly(o-phenylene ethynylene) 522 was reported by Onoda and coworkers [637], As expected, the optical band gap of 522 (3.1 eV) is larger than that of para-connected polymer 516, making the former a blue-purple-emitting material (APL = 400). Interestingly, [Pg.225]

Just as with other conjugated polymers, the emission color of PPE can be tuned by introducing different conjugated fragments in the polymer chain (copolymers 523 and 524) [627,638], Thus, red-orange EL (AEL 590 nm and a shoulder at 530 nm) was reported for the anthracene-based polymer 523 (in PLED ITO/523/A1), whereas [Pg.226]

Bunz demonstrated a facile procedure for the preparation of high quality PAEs by a palladium-catalyzed cross-coupling reaction of acetylene gas with diiodoarenes. The polymerization proceeds at 50 °C, and poly(phenylene-ethynylene)s 114 were produced. Catalyst loadings of 0.1-0.2 mol% of palladium were best to achieve the complete i ... [Pg.672]

The HOMO-LUMO energy gap of some alkoxy substituted poly(phenylene ethynylene)s (ROPPE) is higher than that of the corresponding ROPPVs, indicating that introdu-... [Pg.781]

The chromicity of poly(aryleneediynylene)s (PAE) is discussed and described in diis contribution. Four different types of PAEs will be scrutinized a) dialkyl-poly(para-phenylene-ethynylene)s (dialkyl-PPEs), b) dialkoxy-PPEs, c) acceptor substituted PPEs, and d) heteroaryleneethynylenes that contain benzothiadiazole units in their main chain. We will shortly describe their syntheses and then discuss their spectral properties in absorption and emission in solution and in thin films. [Pg.147]
