Oligo(phenylene vinylene)-poly(methylstyrene) hybrids: Controlled step-wise molecular wiring of oligo(phenylene vinylene)

Well defined oligo(phenylene vinylene) grafted polymers known as oligo(phenylene vinylene)-poly(methylstyrene) hybrids have been developed using a step-wise synthetic protocol, where the length of the OPV can be controlled systematically to achieve specif

Star-Shaped Compounds Having 1,3,5-Triazine Cores

The 1,3,5-triazine derivatives 1-4 having styryl or higher oligo(phenylenevinylene) chains in the 2-, 4-, and 6-positions represent star-shaped push-pull compounds. Alkoxy or dimethylamino groups on the peripheral benzene rings, which act as electron donors, and the central 1,3,5-triazine ring, which acts as an electron acceptor, cause intramolecular charge transfer (ICT) to occur in the absorption S0→S 1. Protonation of the 1,3,5-triazine core enhances the effect, as demonstrated by a bathochromic shift; a secondary protonation on the dimethylamino groups, however, leads to the breakdown of the ICT. Thus, the yellow compound Id first becomes violet and then colorless upon the addition of trifluoroacetic acid. In neutral solution, the long-wavelength absorption of the series 1f, 2b, 3, and 4 converges to λ∞ = 427 nm (with an effective conjugation length nECL = 7). The absorption of the corresponding protonated compounds approaches λ∞ = 515 nm (nECL = 6). Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003.

Practical Synthesis of Vinyl-Substituted p-Phenylenevinylene Oligomers and Their Triethoxysilyl Derivatives

Luminescent semiconducting organic compounds are widely used as active layers in electro-optical devices. Apart from conjugated polymers, monodisperse oligomers also represent attractive materials. The synthesis of stilbenoid oligomers with polymerizable
